Question

hydrochloric acid is solid commercially as a 12.0M solution. how many moles and how many grams of hcl are in 300 ml of 12 M Solution?

Answer 1

no. of moles/0.300L = 12.0 mol/L

no. of moles = 12.0 x 0.300

=3.6 mol.

So, 300mL of the solution contains 3.6 moles of HCl.

Now we can convert the 3.6 moles into grams.

Molar mass of HCl = 36.5 g.

Thus, 3.6 mol in grams will be:

3.6 x 36.5g = 131.4g of HCl in 300mL of the solution.
