Question

What is the mass of 4.5 moles of CO2? Given atomic mass of Carbon =12u and Oxygen =16u

Answer 1

`\huge{ \boxed{ 198 \: \text{g}}}`

Step-by-step explanation:

The mass of
`CO_2` can be found by using the formula;

`m = n * \text{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;

n = 4.5 moles

Molar mass (M) of
`CO_2` = 12 + (16×2) = 12 + 32 = 44 g/mol

`\therefore \: m = 4.5 * 44 = 198 \: g`
