Answer:
221.96 g
Explanation:
Step 1: Given data
Moles of calcium chloride (n): 2 mol
Step 2: Calculate the molar mass of calcium chloride
The molar mass of the compound is equal to the sum of the molar masses of the elements that form it.
M = 1 × M(Ca) + 2 × M(Cl)
M = 1 × 40.08 g/mol + 2 × 35.45 g/mol = 110.98 g/mol
Step 3: Calculate the mass (m) of calcium chloride
We will use the following expression.
m = n × M
m = 2 mol × 110.98 g/mol = 221.96 g
