The molarity of her solution will be 1.88 M

What is Molarity ?

Molarity is defined as the number of moles of solute dissolved in per litre of solution.

Molarity of the solution = number of moles of solute / volume of solution in litre

number of moles of solute = given weight / molecular weight

                                            = 43.3 / 45.95

                                            = 0.942 moles

Now, lets calculate Molarity ;

Molarity of the solution = number of moles of solute / volume of solution in litre

                                       = 0.942 / 0.500

                                       = 1.88 M

Hence, The molarity of her solution will be 1.88 M
