What mass of sodium hydroxide must be di...

What mass of sodium hydroxide must be dissovled in 500 mL of solution so that the strength of the solution may be 10 g/L ?

Text Solution

Verified by Experts

Strength of solution = `("Mass of solute")/("Volume of solution in litres")`
Strength of solution = 10 g/L = `10 gL^(-1)`
Volume of solution = 500 mL = 0.5 L
`therefore` Mass of NaOH (solute) = `(10 gL^(-1)) xx (0.5 L) = 5 g`
