Calculate the molarity of a solution co...

Calculate the molarity of a solution containing `5 g` of NaOH in `450 mL` solution.

Text Solution

Verified by Experts

`M=(W_(2) xx 1000)/(Mw_(2) xx "volume of solution in mL") `
`(5g xx 1000)/(40g mol^(-1) xx 450 mL)`
`=0.278 mol L^(-1)`
`=0.278 mol dm^(-3)`
