What is the mass of 1.5 mol of HCl? (molar mass 36.5 g/mol)

Answer and explanation

Correct answer: C. 54.75 g

  1. Step 1: Mass = moles × molar mass. Step 2. 1.5 × 36.5 = 54.75 g. Answer: 54.75 g. Why not the others: 24.333 g is what you get if you divide the molar mass by the moles. 38 g is what you get if you add the numbers. 5.475 g is what you get if you misplace the decimal point.
