Answer:

$\huge{ \boxed{ \boxed{0.13 \: moles}}}$

Step-by-step explanation:

The number of moles of the given mass of calcium chloride can be found by using the formula;

n = (m)/(M)

where

m is the mass in grams

M is the molar mass in g/mol

n is the number of moles

From the question

m = 14.3 g

Molar mass (M) of calcium chloride (
CaCl_2 ) = 40 + (35 × 2) = 40 + 70 = 110 g/mol

$n = (14.3)/(110) = 0.13 \\$

We have the final answer as
