Question

32.7 g of CuSO4 was dissolved in 100 ml of water. Calculate the mole. pls help​

Answer 1

Answer:

Molarity, M=number of moles/volume of solution

M=

V

n

Number of moles, n=mass/molar mass

Molar mass of CuSO

4

=159.5 g/mole

mass=80g

n=

159.5

80

=0.5 mole

∴M=

3

0.5

=0.167 mole/L
