Question

Calculate the mass of 0.2 moles of water​

Answer 1

Answer:

Explanation:

We know that one mole of water that is H2O is 18 grams

Thus in order to find the weight of 0.2 mole of water we need to multiply the 1 mole of water with 0.2..

That is

18 X 0.2 = 3.6 mole ..

Does the weight of 0.2 moles of the water will be 3.6 grams..

Hope it helps you....

Answer 2

Answer:3.6grams

Explanation:

going with formula of :

no.. of moles=given weight /molecular weight

Can also be written as:

No.. Of moles x molecular weight= given weight(or mass)

So,

no. Of moles=0·2

Molecular weightof water= 18

This mass of 0.2 moles of water = 0·2x18 =3·6g
