The molarity of `H_(2)SO_(4)` is `18 M`. Its density is `1.8 g mL^(-1)`. hence molality is,

A

36

B

200

C

500

D

18

Text Solution

Verified by Experts

The correct Answer is:
C
Use formula
`d = M ((Mw_(2))/(1000) + (1)/(m)) implies 1.8 = 18 ((98)/(1000) + (1)/(m))`
solve for `m:`
`:. M = 500`
