Question

A solution of NaOH in water is labelled as 10% (w/w). The

density of the solution is 2.02 g mL-1

. Calculate the molality.​

Answer 1

Answer:

Correct option is A)

Molarity of compound =MolarmassMassofsolute×V(inmL)1000

Here, Molarity of H2O2=345×1001000=3450=1.5 M

Molarity of solution =1.5 M
