Given : mass of Ca=40
Mass of S = 32
Mass of O= 16
To find : Mass percentage of S in CaSO4
Solution:
We know Mass of -
O=16
S=32
Ca=40
NOW we find total Mass of CaSO4:
=Mass of Ca+Mass of S + 4× Mass of O
= 40+ 32+ 4×16
= 40+ 32+64
= 136
NOW we use formula ,
Mass percentage of S = (Mass of S/ total Mass of CaSO4 compound)× 100
=( 32/136) ×100
=0.235× 100
=23.5%
Answer: Mass percentage of S in CaSO4 is 23.5%
