Question

The mass of 0.32 moles of CaCO3 is equal to? A. 19.2 grams B. 32 grams C. 64 grams D. 96 grams

Answer 1

`\huge{ \boxed{32 \: \text{g}}}`

Step-by-step explanation:

The mass of
`CaCO_3` can be found by using the formula

`m = \text{M} * n`

where

m is the mass in grams

M is the molar mass in g/mol

n is the number of moles

From the question

n = 0.32 moles

Molar mass (M) of
`CaCO_3` = 100 g/mol

`\therefore \:m = 100 * 0.32 =32`

We have the final answer as;

32 g
