I would like to make a solution of magnesium sulfate (MgSO4) that is 15%
magnesium sulfate by mass in water. As magnesium sulfate is sold as epsom salts which is
MgSO4 7H2O I need a way to calculated the epsom salts required for the required
magnesium sulfate or 1.24 pounds per gallon of water (Water at 8.35 pounds per gallon).I am thinking one goes by atomic weight?
For MgSO4:
Mg= 24.3 S= 32.06 Oxgen4= 4* 16 = 64 MgSO4= 120.36
For 7H2O:
7H2 = 7*1*2 = 14 7Oxgen = 7* 16 = 112 7H2O= 126.0
For MgSO4 7H2O= 120.36 + 126.0 = 246.36
So to get 1.24 pounds of MgSO4: 1.24 * 246.36/120.36 = 2.05 pounds perhaps?
Thanks in advance.
