The mass of nitric acid required to make the given solution is 0.0627 g.

The given parameters:

The hydrogen ion (H⁺) concentration of the nitric acid is calculated as follows;

[tex]H^+ = 10^{-pH}\\\\H^+ = 10^{-2.4}\\\\H^+ = 0.00398[/tex]

The molarity of the nitric acid is calculated as follows;

[tex]= 0.00398 \ H^+ \times \frac{1 \ M \ HNO_3}{1 \ H^+} \\\\= 0.00398 \ M[/tex]

The number of moles of the nitric acid is calculated as follows;

[tex]moles = M\times L\\\\moles = 0.00398\ M \ \times \ \frac{250 \ mL}{1000} \\\\moles = 9.95 \times 10^{-4} \ mol.[/tex]

The molar mass of nitric acid is calculated as;

[tex]HNO_3 = (1) \ + (14) \ + (16 \times 3) = 63 \ g/mol[/tex]

The mass of the nitric acid contained in the calculated number of moles is calculated as;

[tex]mass = moles\ \times \ molar \ mass\\\\mass = 9.95\times 10^{-4} \ mol. \ \times \ 63 \ g/mol\\\\mass = 0.0627 \ g[/tex]

Thus, the mass of nitric acid required to make the given solution is 0.0627 g.

Answer:

Silicon Dioxide is a compound usually referred to as Quartz, it's a crystalline sort of material that is commonly found and used for equipment and furniture (like tables for example). Their molecular geometry is of tetrahedral shape (how their bonds look like and such)

Gold is an element that is a transitional metal that is quite malleable (able to hammer it to sheets) and is ductile (can be made into wires). As you probably have guessed, gold is used a lot for jewelry due to its lustrous appearance, and the fact that it can't corrode as well as its rarity. Due to it not being able to corrode, it's pretty useful in circuitry as it requires less management unlike elements with higher electrical conductivity like copper or silver. However gold is pretty costly so it's not often relied on for technology and mostly just used for show instead.

N2 or nitrogen gas, may seem like a compound for people new to chemistry but is actually just a diatomic molecule, meaning they are composed of only 2 atoms. So elements that are diatomic are commonly found with only 2 atoms (Oxygen gas for example, or Hydrogen gas) Nitrogen is part of the "magnificent seven" (the elements which are diatomic".  Nitrogen is essential for a lot of living things (aside from us), and since they are the most abundant material in our air (78% of air is Nitrogen), there's plenty of life growing.

Compound and elements are differ from each other. Silicon dioxide ( SiO₂ ) is compound , gold ( Au ) is  element and nitrogen gas ( N₂ ) is compound.

Elements are always made-up of only one type of atom. Molecule is made up of more than one type of atom. Silicon dioxide is a compound, which is crystalline in nature. Their molecular geometry is of tetrahedral shape.

Gold is an element that is a transitional metal that is quite malleable and is ductile.  Gold ( Au ) is used a lot for jewelry. Nitrogen gas is  compound . It is diatomic in nature, So elements that are diatomic are commonly found with only 2 atoms.

Answer:

17550g

Explanation:

You want to use the equation D=M/V. You are given density in g/mL, so you just need to multiply that by 9L, but first you want the mL and L to match, so you change the 9L to 9000mL (knowing there is 1000mL in 1L). Then solve algebraically by multiplying the 9000mL and the 1.95g/ml, making the mL cancel, leaving you with your answer in grams.

Answer:Amplitude in a longitudinal wave

Explanation:Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. Wave amplitude is determined by the energy of the disturbance that causes the wave. A wave caused by a disturbance with more energy has greater amplitude.

The material that absorbs the heat of the system is water owing to its high specific heat capacity.

The specific heat capacity of a substance refers to the amount of heat that is capable of increasing the temperature of 1 Kg of a body by 1 K. The higher the specific heat capacity, the more the amount of heat that the body can absorb without temperature change.

The material that absorbs the heat of the system is water because water has a higher specific heat capacity than all the other materials present.

The molar mass of NH4NO3 in g/mol is 80g/mol.

HOW TO CALCULATE MOLAR MASS:

The molar mass of a compound can be calculated by summing the atomic masses of its constituent elements.

In ammonium nitrate (NH4NO3), there are nitrogen, hydrogen, and oxygen elements.

Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)

Molar mass of NH4NO3 = 80g/mol

Answer:

Explanation:

Answer:

C6H12O6

Explanation:

First you need to find the empirical formula by the percents that they're giving you. You assume that is 100 grams and if for example you have 40% of carbon you will have 40 grams of carbon.

1.Find the number of moles of each atom

C: 40g÷12g/mol= 3.33 mol

H: 6.7g÷1g/mol= 6.7 mol

O: 53.3g÷16g/mol= 3.33 mol

You divide all ratios by the minimum ratio and you obtain the empirical formula

CH2O

Since you're given the molar mass, you now have to find the molar mass of CH2O by adding the molar mass of each element present and repeated in the compound.

CH2O= 30g/mol

Now you know that the molar mass of the molecular formula we are looking for is 180.18 g/mol, and since the empirical formula is the molecular formula in its smaller ratio, by logic you can say that:

180.18g/mol ÷ 30g/mol= 6

So, you now know that the empirical formula is being multiplied by a factor of 6 to reach a compound with a molar mass of 180.18g/mol, so you multiply each subscript of the empirical formula by 6 obtaining:

C6H12O6
