Calculate the molarity og hudrogen chloride in a solution when `0.365` g of it has been dissolved in 100 mL of the solution .
3 g of a salt of molecular weight 30 is dissolved in 250 g of water . The molarity of the solution is …

Explanation

To solve the problem, we will break it down into two parts:

1. Calculate the molarity of hydrogen chloride (HCl) in the solution.
2. Calculate the molarity of the salt solution.

### Part 1: Molarity of Hydrogen Chloride

**Step 1: Calculate the number of moles of HCl.**
