Question

liquid NaOH dissolved in 500g water the molality will be​

Answer 1

Answer:

molality =no. of moles dissolved per kg water

no. of moles =1

molality =1÷ 0.5

=2

Answer 2

Answer:

VOLUME (Kg) = 500 X 10³

=0.5 Kg

number of moles = 1

$molality(m) \: = \frac{no.of \: moles \: of \: solution}{mass \: of \: solvent \: in \: kg} \\ = \frac{1}{0.5} \\ = 2m$

Hence, molality of the solution is 2m.
