Question

What is the mass of 0.015 moles of NaOH?

Answer 1

Answer:

Mass = 0.6 g

Explanation:

Given data:

Moles of NaOH = 0.015 mol

Mass of NaOH = ?

Solution:

Number of moles = mass/ molar mass

by rearranging this formula,

Mass = number of moles × molar mass

Molar mass of NaOH is 40 g/mol

by putting values,

Mass = 0.015 mol × 40 g/mol

Mass = 0.6 g
