Question

How many atoms of oxygen are in 2.50 moles of co2? is it 1.93 x10^23?

Answer 1

There are approximately 3.01 x 10^24 atoms of oxygen in 2.50 moles of CO2.

Step-by-step explanation:

To determine the number of atoms of oxygen in 2.50 moles of CO2, you need to use the conversion factor based on the balanced chemical equation. The balanced equation shows that there are 2 moles of oxygen atoms for every 1 mole of CO2. Therefore, 2.50 moles of CO2 would contain 5.00 moles of oxygen atoms. To calculate the number of atoms, you can use Avogadro's number (6.022 x 10^23). By multiplying the number of moles by Avogadro's number, you can find that there are approximately 3.01 x 10^24 atoms of oxygen in 2.50 moles of CO2.

Answer 2

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

2.5 mol CO2 ( 2 mol O / 1 mol CO2 ) ( 6.022 x 10^23 atom / mole ) = 3.011 x 10^24 atoms of oxygen
