Question

How many moles of calcium chloride are in 14.3 grams of calcium chloride

Answer 1

`\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

0.13 moles
