What will be the molarity of a solution,...

What will be the molarity of a solution, which contains 5.85g of `NaCl(s)` per 500mL?

A

`4 "mol" L^(-1)`

B

`20 "mol"L^(-1)`

C

`0.2"mol"L^(-1)`

D

`2 "mol"L^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
Since, molarity (M) is calculated by following equation
`"molarity"=("weight"xx1000)/("molecular weight"xx"volume"(mL))`
`=(5.85xx1000)/(58.5xx500)=0.0"mol"L^(-1)`
