4 g of caustic soda (molar mas = 40 g `mol^(-1)`) are dissolved in water and the solution is made to 200 mL. Calculate the molarity of the solution.

Text Solution

Verified by Experts

The correct Answer is:
0.5 M
`"Molarity of solution (M)"=("Mass of solute/Molar mass of solute")/("Volume of solution in litres")`
`=(4g//(40" g mol"^(-1)))/((200//1000)L)=0.5" mol L"^(-1)(0.5 M)`
