Calculate the grams of solute needed to prepare 107 mL of a 2.75 M magnesium chloride solution
Your
Answer

28.02 g

Explanation:

The M stands for molarity. It is moles of solute/liters of solution. We can use the molarity to convert liters to mL, then make a proportion to find the grams.

Now that we have molarity in moles and mL, we can use the 107mL to get moles.

We would multiply moles by molar mass to get grams. The molar mass of magnesium chloride is 95.211 g/mol.

yes the answer is total mass in unchanged   : )
