Question

What is the percent composition by mass of sulfur in the compound mgso4

Answer 1

26.7% is the percent composition by mass of sulfur in a compound named magnesium sulfate.

Step-by-step explanation:

Molar mass of compound = 120 g/mol

Number of sulfur atom = 1

Atomic mass of sulfur = 32 g/mol

Percentage of element in compound :

`=\frac{\text{Number of atoms}* \text{Atomic mass}}{\text{molar mas of compound}}* 100`

Sulfur :

`=(1* 32 g/mol)/(120 g/mol)* 100=26.7\%`

26.7% is the percent composition by mass of sulfur in a compound named magnesium sulfate.
