Magnesium uses

Magnesium (Mg) has several important metabolic functions in the production and transport of energy. It is also important for the contraction and relaxation of muscles. Magnesium is involved in the synthesis of protein, and it assists in the functioning of some enzymes.

Magnesium Sulphate Heptahydrate is an inorganic compound made of magnesium, sulphur and oxygen. Also known as Epsom salt, this powdered substance is widely used in Agriculture and Horticulture (technical grade) fields to improve the soil fertility levels. Moreover, it is use in the chemical and animal sector.

Chemically is also used to make pain relieving lotions, creams and oils. This chemical is mildly soluble in alcoholic substances and available in bulk quantity in the seawater.(technical grade)

For animal, it is important in the metabolism of carbohydrates, lipids (fats) and protein. Also used for nerve activity and muscle contraction.(feed grade)

Magnesium and sulfur, two naturally occurring minerals that are major components of Epsom salt, may help plants grow greener with higher yields and more blooms. Magnesium creates an environment conducive to growth by helping seeds to germinate, increasing chlorophyll production and improving phosphorus and nitrogen uptake. Sulfur is also a key element in plant growth, helping produce vitamins.(feed grade)


What is the mass percent of water in magnesium sulfate heptahydrate?


The percentage  by mass of water in magnesium sulfate heptahydrate is 51.2 %


Step 1: Data given

Molar mass of MgSO4*7H2O = 246.5 g/mol

Molar mass of H2O = 18.02 g/mol

Molar massof MgSO4 = 120.37 g/mol

Step 2: Calculate % water in magnesium sulfate heptahydrate

Since we have 7 molecules of water in the heptahydrate, we will divide the molar mass of 7 molecules water by the molar mass of the heptahydrate.

m%(H2O) = (7*18.02)/ 246.5

m%(H2O) = (126.14 /246.5)*100%

m%(H2O) = 51.2 %

To controle this we will calculate the mass % of MgSO4

m%(MgSO4) = (120.37/ 246.50)*100%

m%(MgSO4) = 48.8%

51.2 + 48.8 = 100%

The percentage  by mass of water in magnesium sulfate heptahydrate is 51.2 %
