Answer:
33.30 grams of CaCl2 will be required
Explanation:
Given,
Volume of solution, V= 250 ml
Molarity of solution, M= 1.20 mol/L
Molecular mass of CaCL2, S= 40+(35.5 X 2)= 111
We know,
Required mass, W= SVM/1000
Now,
W = (111 X 250 X 1.20)/1000
= 33300/1000
= 33.30
Therefore, 33.30 grams of Calcium Chloride will be required.

What is molarity?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Molar mass of = 0.762 mol
Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L
Solution:
Step 1: Calculating moles of
• Molarity =
• Putting the value in the given formula
• Moles of solute C8H18 = 
• Moles of solute C8H18 = 
Now,
Molarity =
Molarity =
Molarity =
Hence, is the of is in 405,576.398 mL.
