Answer: PLease see answer in explanation column
Explanation:
FIRST STEP
We find the grams ( mass ) of solute required to prepare the solution by using the formula
grams ( mass ) of solute, g(CaCl2)= Molar mass x Molarity of the solution x Volume of the solution
Therefore Preparing 750 mL of 1.5 M calcium chloride solution, we have that Molar mass of Calcium chloride =110.98 g/mol
g(CaCl2) =110.98 g/mol X 1.5mol/L X 0.75L
g(CaCl2) =124.8525g CaCl2
SECOND STEP
Now Dissolve 124.8525g CaCl2 in about 350ml of distilled water then add more water until the final volume be comes 750ml
