Question

What mass of iron (II) sulfate is found in 75mL of 5%w/V solution

Answer 1

5 % w/V iron (II) sulfate solution means

100 ml solution have 5 g of iron(II) sulfate

1 ml solution have = 5/100 g of iron(II) sulfate

75 ml solution have = (5/100)×75 g of iron(II) sulfate

=3.75 g iron(II) sulfate

Hence, 3.75 g of iron (II) sulfate is found in 75mL of 5%w/V solution
