Answer:
MgSO4
Mg= 20.19%
S= 26.64%
O= 53.16%
Explanation:
MgSO4
Mg=24.31 g/mol
S=32.07 g/mol
O=16 g/mol
Total molar mass= (24.31)+(32.07)+4(16) g/mol
Total Molar mass=120.38 g/mol
Percentage composition= element molar mass/total molar mass x 100%
Mg= 24.31/120.38 x 100 = 20.19%
S= 32.07/120.38 x 100 = 26.64%
O= 64/120.38 x 100 = 53.16%
