Determine the number of grams of NaCl necessary to make up 100 mL of a 0.10 M solution.

0.017 g

0.58 g

1.7 g

58 g

Molarity is obtained by dividing the number of moles by the volume of the solution in liters. Therefore, the number of moles is the product of molarity and volume.

n = (100 mL) x (1 L / 1000 mL) x (0.10 M) = 0.01 moles

Multiply this value with the molar mass of NaCl to obtain the amount of substance in mass,

m = (0.01 moles) x (58.45 g / mol) = 0.5845 g
