What is mole fraction of methyl alochol in a 5.2 molal aqueous solutio

1.	What is mole fraction of methyl alochol in a 5.2 molal aqueous solution of methyl alcohol, CH_(3)OH.
Answer» 0.1 0.19 0.086 0.05 Solution :5.2 MOLAL methanol. `:.` 5.2 MOLE of methanol in 1000 G WATER. Mole of water `= (1000)/(18) = 55.56` TOTAL mole `= 5.2 + 55.56 = 60.76` Mole fraction of methanol `=("mole of methanol")/("total mole")` `= (5.2)/(60.76) = 0.08558 ~~0.086`
