Question

Calculate the percentage of water present in mgso4, 7h2o

Answer 1

%H20=

(14xH)+(7xO)

______________________________ X 100

(Mg) + (S) + (4 x O) + (14 x H) + (7 x O)

Thus,

(14 x 1.008) + (7x16.0)

______________________________________ X 100

24.31 + 32.06 + (4x16.0) + (14 x 1.008) + (7x16.0)

=126.122

_____________ X 100

246.482

= 0.512 x 100

=51.2%

There is 51.2% of water is Magnesium Sulphate-7-water.
