Question

If 20g of methanol (CH^3OH) [density =0.8g/cc] is added to 30g of glycol [density =1.4g/cc] . find the molarity of the solution?​

Answer 1

Explanation:

Number of moles of methanol =3230×0.8=0.75

Number of moles of ethanol =4660×0.92=1.2

Mole fraction of solute methanol =0.75+1.20.75=0.385

Mole fraction of solvent ethanol =1−0.385=0.615

Molality of solution =1.2×460.75×1000=13.59 m
