Question

What molarity is made when 36.5 g HCl is mixed into 250 mL of solution?​

Answer 1

The molarity of the HCl solution is 4M.

Step-by-step explanation:

`Molarity=(number\:of\:moles)/(Volume\:of\:solution\:in\:L)\\ \\The\:volume\:of\:solution=250mL=0.25L\\\\Number\:of\:moles=(weight\:of\:HCl\:in\:solution)/(molecular\:weight\:of\:HCl)\\ \\Molecular\:weight\:of\:HCl=36.5g\\\\The\:weight\:of\:HCl\:in\:solution=36.5g\\\\Number\:of\:moles\:of\:HCl=(36.5)/(36.5)=1\:mole\\\\The\:molarity\:of\:HCl\:solution=(1)/(0.25)=4M`

Hence, the molarity of the HCl solution = 4 M
