To find the mass you need to find the weight of a mol of the molecules by adding up the atomic mass.

N = 14.007 g/mol
H = 1.008 g/mol
S = 32.065 g/mol
O = 16 g/mol

2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol

Now you know how much an entire mol weight you multiply it by how much you actually have

0.00456 * 132.143 = 0.603 g

A solution is prepared by dissolving 8.75 grams of sodium chloride in enough volume of water to produce 112.0 grams of the NaCl

ICE Princess25 [194]

Answer : The percent by mass of the solution is 7.81 %

Explanation : Given,

Mass of NaCl = 8.75 g

Mass of solution = 112.0 g

Now we have to determine the percent by mass of the solution.

$\text{Mass percent}=\frac{\text{Mass of NaCl}}{\text{Mass of solution}}\times 100$

Putting values in above equation, we get:

$\text{Mass percent}=\frac{8.75g}{112.0g}\times 100=7.81\%$

Therefore, the percent by mass of the solution is 7.81 %
