Question

500mL of 3% alician blue in 1% acetic acid, calculate the solute needed

Answer 1

Ans :

Here alician blue and acetic acid are solutes and water is solvent.

Mass percentage of alician blue = ( mass of alician blue / volume of solution ) x 100

putting values :

3 = ( m / 500 mL ) x 100

m = 15 g

volume % of acetic acid = ( volume of acetic acid / volume of solution ) x 100

putting values :

1 = ( v / 500 mL) x 100

V = 5 mL

so 15 g alician blue and 5 mL acetic acid is needed.
