How much CaCO3 and water must be wieghed to make a solution that is 10% CaCO3?
10g, 90g
5g, 95g
20g, 80g
15g, 85g
As we learnt
Mass percent of solution -
Mass percent = ((mass of solute)/(mass of solution) ) X 100
- wherein
it is mass of solute present in 100 gram solution.
Mass of CaCO3 is 100g of solution =10g
Mass of water =100-10=90 g
Option 1)
10g, 90g
Option 2)
5g, 95g
Option 3)
20g, 80g
Option 4)
15g, 85g
