please explain with steps​

Answer 1

Answer:

Percent composition by element

Element Symbol Mass Percent

Magnesium Mg 20.192%

Oxygen O 53.168%

Sulfur S 26.639%

Answer 2

Answer:

molar mass of MgSO4

    = 24.30+32+4×16

    = 24.30+32+64

    =  120.30g

mass percentage of mg

   = $\frac{24.30}{120.30}$ ×  100

   =$\frac{2430}{1203}$ ×  10

   =$\frac{24300}{1203}$ =  20.19%

So the final answer is 20%
