What is the concertration of copper sulphate (in mol `L^(-1))` if 80 of it is dissolved in enough water to make a final volume of 3 L?

A

0.0167

B

0.167

C

1.067

D

10.67

Text Solution

Verified by Experts

Molar mass of `CuSO_4` = 63.5+32+64=159.5
Moles of `CuSO_4=(80)/(159.5)=0.50`
Volume of solution = 3L
Molarity `=("Moles of solute")/("Volume of solution in L")=(0.50)/(3)`
`=0.167mol L^(-1)`
