Rex Villanueva · Answer 1

0.035 mole

Explanation:

To solve this problem, let us calculate the molar mass of NaOH. This is illustrated below:

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

Mass of NaOH from the question = 1.4g

Number of mole of NaOH = ?

Number of mole = Mass / Molar Mass

Number of mole of NaOH = 1.4/40

Number of mole of NaOH = 0.035 mole.

Therefore, 0.035 mole of NaOH is present in 1.4g of NaOH.
