Question

What is the molarity of a solution that contains 25 g of hcl in 150 ml of solution? (the molar mass of hcl is 36.46 g/mol.) what should you find first?

Answer 1

Answer: 4.6 M

Explanation:

Converting 25 g of HCl to moles, we get 25/36.46 = 0.68568294020845 moles.

Also, 150 mL = 0.150 L

So, the concentration is:

$\frac{0.68568294020845}{0.150} =\boxed{4.6 \text{ M}}$
