A gas at 131.0 kPa and 28.0°C fills a flexible container with an initial volume of 2.88 L. If the temperature
is raised to 69.4°C and the pressure increased to 451.0 kPa, what is the new volume in Liters?

0.837
0.723
0.952
O 0.761

Answers

Answer 1

Apply combine gas law

P1V1/T1=P2V2/T2131(2.88)/(273+28)=451V2/(273+69.4)131(2.88)/301=451V2/341.6V2=10.2L

1. At constant temperature, the volume of a gas was found to be 500cm³ at a pressure of 760mmHg. If the pressure of the gas is doubled what will be the new volume of the gas?​

Answers

Answer:

SEE BELOW

Explanation:

Given   500 cm^3 = V1    760 mm = P1     (760*2) = P2

Required   V2

P1V1 = P2V2

RE-ARRANGE  TO    P1V1/P2 = V2

(760)(500) /(760*2) = V2

V2 = 250 ML

According to Boyles law

[tex]\\ \rm\Rrightarrow P\propto \dfrac{1}{v}[/tex]

So if pressure is increased volume will be decreased and vice versa

Now pressure is doubled means multiplied by 2

The volume will be divided by two of get halved .

what volume of a 0.25M solution can be prepared with 28.5g of k2s? (molar mass=110.26g)

Answers

Answer:

volume = 1.04 dm^3

Explanation:

Data:

volume = ?

Molarity, M = 0.25M

mass = 28.5g

Molar mass = 110.25g

Moles = ?

Solution:

First find number of moles,

 moles = mass in gram / molar mass

             = 28.5 / 110.25

              = 0.258

              ≈ 0.26 moles

Now,

          Molarity = [tex]\frac{no. of moles}{volume in dm^3}[/tex]

So,

           Volume in dm^3 = [tex]\frac{no. of moles}{molarity}[/tex]

                                       =  0.26 / 0.25

                         Volume  = 1.04 dm^3

The concentration of an unknown protein sample was determined as 8.3 mg/ml. Calculate the concentration of the unknown protein in mM (millimolar) if: Average molecular mass of an amino acid = 118 g/mol The protein is 64 amino acids in length.

Answers

Based on the molar mass of the protein, the concentration of the unknown protein is 0.0011 mM (millimolar).

What is concentration?

Concentration is the amount of a solute present in a given volume of substance.

Concentration = moles/volume

Moles of protein = mass/molar mass

molar mass of protein = 118 × 64 = 7552 g/mol

Moles of protein in 8.3 g = 8.3/7552 = 0.0011 moles

Concentration = 0.0011 mole/mL = 0.0011 mM.

Therefore, the concentration of the unknown protein is 0.0011 mM (millimolar).

A truck tire at 82.0L at 32.5°C and 1.9 atm has a temperature change to-15.4°C and a pressure change to 770.0 mmHg. Calculate how much the volume of the
air in the tire will change.

Answers

Answer:

+ 47.68 Liter change in volume to final volume 129.68 L

Explanation:

P1V1/T1 = P2V2/T2     RE-ARRANGE TO:

P1V1/T1  * T2/P2  = V2         (T must be in Kelvin)

1.9 * 82 / (273.15 + 32.5)   *  (273.15-15.4)/ (770/760) = 129.68 L

What is volume?

A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that may be used to indicate volume, the most common ones are liters, m³, gallons, milliliters, teaspoons, as well as ounces.

Gases have a volume equal to the internal capacity of the container since they fill their containers to the brim. Containers with a designated volume or one whose interior form is known are frequently used to measure liquids. Measuring cups, graded cylinders, flasks, as well as beakers are a few examples of the tools used to quantify liquid volume.  3.0x10⁻¹²kiloliters represents the greatest volume.

Therefore, the correct option is option C.
