Answer: 64.1 ml of concentrated is taken and (250-64.4)= 185.6 ml f water is added to make 250.00 mL of 3.00 M HCl .
Explanation:
Given : 36 g of is dissolved in 100 g of solution.
Density of solution = 1.18 g/ml
Thus volume of solution =
where,
n= moles of solute
= volume of solution
According to the dilution law,
where,
= molarity of stock solution = 11.7M
= volume of stock solution = V ml
= molarity of diluted solution = 3.00 M
= volume of diluted solution = 250.0 ml
Thus 64.1 ml of stock is taken and (250-64.4)= 185.6 ml of water is added to make 250.00 mL of 3.00 M HCl .
