Question

What is be the molarity of solution cantain 18.25 g of HCl gas in 500g of water

Answer 1

Explanation:

Given, mass of HCL=18.25 g =18.25×10^-3

volume of solution =

500g=500ml=500×10^-3dm3

molarity =?

molar mass of HCL =36.5×10^-3

molarity =mass of HCL÷molar mass of HCL×volume of solution

molarity = 18.25×10^-3÷36.5×10^-3×500×10^-3

= 0.25moldm3
