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
