Question

What mass of sodium hydroxide is dissolved in 500ml of solution so that the strength of solution may be 10 g /l

Answer 1

Answer:

Solution :                        Mass of solute

Strength of solution =Volume of solution in litres

Strength of solution = 10 g/L = 10gL−1

Volume of solution = 500 mL = 0.5 L

∴ Mass of NaOH (solute) = (10gL−1)×(0.5L)=5g
