Question

Calculate the number of grams-formula weights in 50 g of NaCl

Answer 1

The formula for calculating the gram molecular mass of a substance is:

gram-formula mass = mass of the solute / molecular weight

From here, the number of grams-formula weights of NaCl equals:

gram formula mass = 50 g / 58.44 g/mol = 0.86 mol

Answer: 0.86 mol
