What will be the molarity of a solution ...

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

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
Molarity (M) `= (("5.85 g")//("58.5 g mol"^(-1)))/("(500/1000)L")`
`=(0.1)/(0.5)=0.2 "mol L"^(-1)`
