<u>Answer:</u> The molality of solution is 0.782 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molality:
.....(1)
Given values:
Moles of = 0.395 mol
Mass of solvent (water) = 0.505 kg
Putting values in equation 1, we get:
Hence, the molality of solution is 0.782 m
262mol 1=kg
g=1000
from stoichoimetry
x=102*1000/360
x=102000/360
x=283.33
density =m/v
=283.33/1.082
=262mol
g=1000
from stoichoimetry
x=102*1000/360
x=102000/360
x=283.33
density =m/v
=283.33/1.082
=262mol
