Question

0.08g of hydrogen calculate no. of atoms

Answer 1

1 g ---6.022x10²³
0.08 g-----?

6.022x10²³ X 0.08 = 0.4817 X 10²³= 4.81 x 10²⁴(atoms of hydrogen)

Answer 2

Given: 0.08g of hydrogen.

To find: We have to find the number of atoms.

Solution:

To determine the number of atoms in 0.08g of hydrogen we have to follow the below steps-

The mass of the H atom is 1g.

Thus we can write that 1g of the hydrogen atom has $6.023×10^{23}$ number of atoms.

Thus 0.08g of H atom has $6.023×10^{23}×0.08=0.48×10^{23}$ number of atoms.

Thus 0.08g of H atom has $0.48×10^{23}$ number of atoms.
