Conc. HCl is `38%` HCl by mass. What is the molarity of this solution is d=1.19 g `cm^(-3)`? What volume of conc. HCl is required to make 1.00 L of 0.10 M HCl?

Text Solution

Verified by Experts

`M =W_(a)/M_(b) xx 1000/("Vol. of solution in ml")`
`M= 38/36.5 xx 1000/(("Mass of solution")/("Desnsity of solution")) = 38/36.5 xx (1000 xx 1.19)/10 = 12.39` M.
