What is the mass of 1.5 mol of NaOH? (molar mass 40 g/mol)
Answer and explanation
Correct answer: C. 60 g
- Step 1: Mass = moles × molar mass. Step 2. 1.5 × 40 = 60 g. Answer: 60 g. Why not the others: 26.667 g is what you get if you divide the molar mass by the moles. 41.5 g is what you get if you add the numbers. 6 g is what you get if you misplace the decimal point.
