Question

The molecular mass of so2 is 64
(1) find the mass of 1gmm so2
(2) find the number of molecules in 1gmm so2
(3) find out the number of mole of molecules in 320g of so2

Answer 1

Answer:

Now, we get 64 gm of SO2 have 1 mole of SO2 molecules. Also 1 molecule of SO2 consists of 3 atoms ( 1 of Sulphur and 2 of oxygen). So, 1 mole of SO2 = 6.023× 10^23 molecules of SO2 = 3× (6.023× 10^23) atoms = 18.069× 10^23 atoms. Note: 1 mole of anything = 6.023× 10^23 anything.
