Answer:
2.5M
Explanation:
Molarity is the measure of the molar concentration of a solution. It is calculated using the formula below:
Molarity = n/V
Where;
n = number of moles (mol)
V = volume (L)
According to the information about Calcium chloride (CaCl2) provided in this question;
n = 0.5moles
M = 0.20M
Molarity = 0.5/0.2
Molarity = 2.5M
