# Calculate the molarity of the NaCl solution when 29.2 g of NaCl is dissolved in 100 mL of water.

## Question:

Calculate the molarity of the NaCl solution when 29.2 g of NaCl is dissolved in 100 mL of water.

## Number of Moles, Molar Mass, and Molarity:

The number of moles can be calculated as the fraction of the mass of the substance to the molar mass of the substance. Molar mass is the mass of the substance in one mole. The molarity of the solution is the fraction of the number of moles to the volume of the solution.
