Question

no. of moles in 36ml of water.​

Answer 1

Number of moles = 36/18 = 2 moles. 3. One molecule of H2O has two hydrogens,so 2 moles of water has 2N atoms of H.

Answer 2

36 grams of water occupy 2 moles.

Given:

36 ml of water.

To find:

The number of moles.

Solution:

To determine the number of moles we have to follow the below steps-

36 ml of water is equal to 36 grams of water as the density of water is 1 gram per cc.

The molecular weight of water is 18 grams.

Thus we can write-

18 grams of water occupy 1 mole.

So, 36 grams of water occupy 36/18=2 moles.

So, 36 grams of water occupy 2 moles.
