Question

If 40.0 grams of HCI were dissolved in enough water to make a solution with a total volume of 3.0 liters, what would be the molarity of the solution?

Answer 1

Answer: 0.37 M

Step-by-step explanation:

HCl has a gram-formula mass of 36.46 g/mol, so 40.0 g is about 40.0/36.46=1.10 mol.

This means that since molarity = (moles of solute)/(liters of solution), the answer is 1.10/3.0 = 0.37 M
