8g NaOH is dissolved in water and the solution is made upto 500 mL. find the molarity of solution.

Text Solution

Verified by Experts

Number of moles of `NaOH=("given mass")/("molecular mass")=(8)/(40)=0.2`
`therefore`Molarity (M)`=("number of moles of NaOH")/("volume of solution (L)")=(0.2)/(0.5)=0.4`
