Question

what amount of MgSo4 will be required to prepare 0.5 Molar solution of Mgso4?

Answer 1

Answer:

mass of mgso4= 120g

molarity=0.5M

so we have to add 0.5 moles of mgso4 in 1 litre of water to make a 0.5 M solution..

so M=(given mass/molar mass)*volume of soil/1000

0.5= m/120*1

m=120*0.5

m=60g

you need 60g of mgso4...

hope u understand..
