Question

calculate the molarity of solution containing 5gram of NaOH in 450 ml solution​

Answer 1

Answer:

the answer for this question is 0.55 mol/lit

Explanation:

no of moles of naoh = given weight/mol weight

=5/40 = 1/8 =0.25

volume of solution = 0.45 litres

molarity = no. of moles of solute/vol of solution

therefore 0.25/0.45 = 0.55
