What is the mass of 2 mol of KOH? (molar mass 56 g/mol)

Answer and explanation

Correct answer: A. 112 g

  1. Step 1: Mass = moles × molar mass. Step 2. 2 × 56 = 112 g. Answer: 112 g. Why not the others: 28 g is what you get if you divide the molar mass by the moles. 58 g is what you get if you add the numbers. 11.2 g is what you get if you misplace the decimal point.
