Question

calculate the number of moles in 11.2 litre of chlorine​

Answer 1

Answer:

1 mole occupies 22.4 litre at stp

thus 11.2 litres contains =11.2/22.4 = 0.5 moles

1 mole contains 6.023 * 10^23 molecules

thus 0.5 mole contains= 0.5 *6.023*10^23=3.0115*10^23 molecules

1 molecule contains 2 atoms

3.0115*10^23 molecules contain=2*3.0115*10^23=6.023 * 10^23 atoms!
