Find the mass. 2.40 mol NaOH

5.6 mol

Answer: 96g

Explanation:

To find the mass of 2.40mol of NaOH, we must first obtain the molar mass of NaOH. This is illustrated below:

Molar Mass of NaOH = 23 + 16 + 1 = 40g/mol

From the question, we were asked to find the mass of 2.4moles of NaOH. This is done by the formula:

Mass = number of mole x molar Mass

Mass of NaOH = 2.4 x 40

Mass of NaOH = 96g
