Find the molarity of a solution made by dissolving 3.84 g calcium bromide in 250.0 mL total solution.

Question

PLEASE HELP. I've cried over this twice and I just don't understand. Thank you in advance.

Answer 1

Hii don't cry I can help you with this:-

Molarity = moles of solute / Liter of solution

so first we have to find the moles of solute = given mass / Molar mass

= 3.48/199.98

= 0.017401 moles

Molarity = 0.017401/ 0.250

=0.069 M

Thank you
