Question

How many molecules are in 3.4 moles of CO2

Answer 1

2.04782 x 10²⁴ molecules

Step-by-step explanation

According to Avogadro,

1 mole of any substance contains 6.023 × 10²³ molecules

So 3.4 moles of CO2 will contain

`\frac{3.4\text{ }mol}{1\text{ }mol}*6.023*10^(23)\text{ }molecules=2.04782*10^(24)\text{ }molecules`

There are 2.04782 x 10²⁴ molecules of CO2 in 3.4 moles of CO2.
