How many grams of sodium hydroxide, NaOH, are needed to make 355.0 mL of a 4.75M solution? The molar mass of NaOH is 40.00 g/mol
Answer:
4198.97404999
Explanation:
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

What is the mass of NaCl required to make 160 grams of a 12% solution of NaCl in water?
18 grams
19 grams
22 grams
24 grams
Answer: 19 grams
Explanation:
percent by mass = (mass of part)/(mass of whole) * 100
this means that in this question, 12 = x/160 * 100, where x is the amount of NaCl.
this means 12/100 = x/160, and thus x = (160)(12/100)=19.2 grams
The closest option is B.
Answer:
Second Option: 19 grams
Explanation:
Total solution weight: 160 grams
percent of NaCl in the solution: 12%
You take these two numbers and multiply them with 12 being over 100:
160 * [tex]\frac{12}{100}[/tex] = 19.2 grams
and then just round to the nearest whole number: 19 grams
Convert these temperatures to Celsius:
a. 303 K
d. 45 K
303K − 273.15 = 29.85°C
45K − 273.15 = -228.1°C

V. What volume of nitric oxide will diffuse out of a porous partition in 10 seconds when 25 ml of methane diffuse out in 4 seconds?
The volume of nitric oxide that will diffuse out of the partition in 10 seconds when methane diffuses is 62.5 mL
What is rate of diffusion?This is defined as the amount diffused per unit time. Mathematically, it can be expressed as
Rate = volume / time
How to determine the rate of diffusion of methaneVolume of methane = 25 mLTime = 4 sRate = ?Rate = volume / time
Rate = 25 / 4
Rate = 6.25 mL/s
How to determine volume of nitric oxideTime = 10 sRate = 6.25 mL/sVolume of nitric oxide = ?Rate = volume / time
6.25 = volume of nitric oxide / 10
