15grams of methyl alcohol is dissolved ...

` 15grams ` of methyl alcohol is dissolved in ` 35 grams `of water . What is the mass percentage of methyle alcohol in solution?

A

0.3

B

0.5

C

0.7

D

0.75

Text Solution

Verified by Experts

The correct Answer is:
A
Total mass of solution = (15 + 35) gram = 50 gram
mass percentage of methyl alcohol
`=("Mass of methyl alcohol")/("Mass of solution") xx100`
`15/50xx100=30%`
