Question

How many molecules are in 4.5 moles of CO2?

Answer 1

Answer:

2.71 × 10^24 molecules

Explanation:

We are given;

Moles of CO₂ as 4.5 moles

We are required to determine the number of molecules

From the Avogadro's constant;

1 mole of a molecular compound contains 6.022 × 10^23 molecules

Therefore;

Molecules of CO₂ = Moles of CO₂ × Avogadro's constant

That is;  

               = 4.5 moles × 6.022 × 10^23 molecules/mole

               = 2.71 × 10^24 molecules

Hence, 4.5 moles of CO₂ contains 2.71 × 10^24 molecules

Answer 2

Avogadro's constant is a proportionality factor, which relates to the number of units in one mole of any substance. The value of Avogadro constant is 6.022 $\times 10^{23}$.

Given that:

Moles of CO₂ = 4.5 moles

Number of molecules = ?

Avogadros constant = 6.022 $\times 10^{23}$

Molecules in the Carbon dioxide can be calculated as:

Molecules of CO₂ = Moles of carbon dioxide x Avogadro constant

Molecules of CO₂ = $4.5\times 6.022$ $\times 10^{23}$

Molecules of CO₂ = $2.71 \times 10 ^{24}$ molecules

Thus, the 4.5 moles of carbon dioxide will have  $2.71 \times 10 ^{24}$ molecules.
