100 ml of ethylalcohol is made upon a litre with distilled water. If the density of `C_(2)H_(5)OH` is `0.46gr//ml`. Then its molarity is

A

0.55m

B

1.11m

C

2.22m

D

3.33m

Text Solution

Verified by Experts

The correct Answer is:
B
`m=("wt of solute")/("G.M. wt")xx(1000)/("wt of solvent in gm")`
`"wt of solute"=dxxv` `=46gm`
`"Volume of solvent"=900ml`
`therefore" wt of solvent"="900 gms"`
`"(density of water = 1 gm 1 C.C)"`
