Question

How much water should be added to 10 g of common salt to obtain 10% salt solution ?

Answer 1

3.3g H2O will be required

Answer 2

Answer:

Explanation:concentration of salt solution =10%

Mass of common salt=10g

Concentration of salt solution =mass of solute /mass of solution ×100

Solution =solute +solvent

10%=10/10+x ×100

10=10×100/10+x

10=1000/10+x

10(10+x)=1000

100+10x=1000

10x=1000-100=900

x=900/10

=90
