Question

123.2g of naoh is dissolved in 1 kg of water calculate molality​

Answer 1

Answer:

molality = 3.08

Explanation:

weight of NaOH = 123.2 gram

molecular mass of NaOH = 40

so molality = $\frac{moles of NaOH}{mass of solvent in kg}$

                  = $\frac{(123.2/40) }{1}$

                  = 3.08 molal
