Question

How do you convert 0.45 g of sodium hydroxide, NaOH to moles?

Answer 1

Answer:0.0113mol

Explanation:

Given:-

Given mass of substance=0.45g

Molecular mass of NaOH=40g

(Molecular mass of

Na=23g,O=16,H=1

By adding all we will get =40g)

Now ,we know that

No.of moles =given mass/molecular weight

So, putting the values

n=0.45/40=0.0113mol

Answer 2

Answer:

Explanation:

It is easy: No. Of moles=given mass ÷ molar mass(sum of atomic masses of all elements present in compound)

So: Moles of NaOH=0.45 ÷ 40(23+16+1)=0.0112
