Answer 1

Good morning dear....


Number of moles=Molar mass


Molar mass of NaOH =40 gmol-1.
Therefore,

Number of moles=60g
40g mol-1
= 1.5 mol.

I hope it's helps u alot..




thank u....

Answer 2

Here is your answer....

Molecular mass of NaOH = 23 + 16 + 1 = 40

No. of moles = w/M = 60/40 = 3/2 = 1.5

Number of moles in 60g NaOH = 1.5

I hope it helps you ^_^
