If 4.89 g of ZnCl₂ is dissolved in enough water to give a total volume of 500 mL,what is the molarity of the solution? A) 0.217 M B) 0.0179 M C) 0.0717 M D) 1.33 M E) 0.849 M

Question

We first need to calculate the number of moles of ZnCl2 in the solution:

moles of ZnCl2 = 4.89 g / (136.29 g/mol) = 0.0359 mol

Then, we can use the formula for molarity:

Molarity = moles of solute / liters of solution

Since we have 500 mL (or 0.5 L) of solution, we can calculate the molarity:

Molarity = 0.0359 mol / 0.5 L = 0.0717 M

Therefore, the best choice is C.
