Question

Find the molecule number of H and O in 1.8 g H20​

Answer 1

Number of molecule of H = 2

and oxygen = 1

Answer 2

Answer:

number of H and O in 1.8 g H20

6.023 *10^23 * 1.8/18 = 6.023 * 10^22

explanation

One molecule of water contains 10 electrons. One mole of water molecules will contain 10N

A

electrons. Here, N

A is the Avogadro number.

1.8 g of water molecule corresponds to

18

1.8

=0.1 mole. Thus, 0.1 mole of water molecule contains 0.1×10N

A

=N

A

electrons = 6.022×10 ^ 23
