&>>

MOlar mass of NaNO3 id 85. density of the solution is ... As we have given 1 M solution of NaNO3, it means 1 mole

Answer 2

Answer:

Calculate the molality of 1m solution of NaCl having density of 1.05

Explanation:

==========

Molality = mole of Nacl/wt.of solvent in kg

__________________________________

wt.of solvent = wt.of solution -wt of NaCl

__________________________________

=1.05×1000-58.5

_________________

=105.0-58.5 =1000g =1kg

______________________

m =1/1 =1
