Question

Calculate the number of particles in each of the following:

i) 24 g of carbon. (number of atoms)

ii) 4 g of oxygen molecules.(number of molecules)

iii) 10 moles of water.(number of molecules)​

Answer 1

Answer:

There are 12.044 X 1023 carbon atoms in 24 grams of carbon.

4g of oxygen have 7.52 × 1022 molecules.

10 moles of water molecules = 10 × (6.022 × 1023) = 6.022 × 1024 water molecules.

Answer 2

Answer:

1.There are 12.044 X 1023 carbon atoms in 24 grams of carbon.

2.Hence, 4g of oxygen have 7.52 × 10²² molecules.

3.10 moles of water molecules = 10 × (6.022 × 10²³) = 6.022 × 10²⁴ water molecules.
