Question

Calculate percentage of sulphur present in CuSo4.5h2O and show your working

Answer 1

Answer:

13.06% Sulphur is there in the compound.

Explanation:

Atomic Mass of Copper = 64 u

Molecules of Copper = 1

Atomic Mass of Sulphur = 32 u

Molecules of Sulphur = 1

Atomic Mass of Oxygen = 16 u

Molecules of Oxygen = 9

Atomic Mass of Hydrogen = 1 u

Molecules of Hydrogen = 5

So,

Total Atomic Mass = (64*1)+(32*1)+(16*9)+(1*5) u

= 64+32+144+5 u

= 245 u

Percentage of Sulphur = (32/245)*100 %

= 13.06%

Hope this helps.
