CALCULATE THE NUMBER OF MOLECULES PRESENT IN
1. 32 g of so2
2. 128g of pcl5
3. 50g of caco3
1 mole = 6.023 x 1023 molecules
SO2 = 32/64 = 0.5 mole = 0.5 x 6.023 x 1023 molecules
= 3.0115 x 1023 molecules
PCl5 = 128/216.5 = 0.59 mole = 0.59 x 6.023 x 1023 molecules
= 3.56 x 1023 molecules
CaCO3 = 50/100 =0.5 mole = 0.5 x 6.023 x 1023 molecules
= 3.0115 x 1023 molecules
