Answer:
1 mole of [na2co3.10h20] known as washing soda contains 6.022*10^23 molecules.
Hence 0.2 moles will contain- 6.022*10^23*0.2 molecules
=1.2044*10^23 molecules.
1 molecule of washing soda contains 13 atoms of oxygen [according to chemical formula]
hence 1.2044*10^23 molecules will contain
- 13*1.2044*10^23 atoms of oxygen
=15.6572*10^23 atoms of oxygen..
