Question

How many oxygen atoms are in 0.50 moles of co2

Answer 1

The number of molecules present in 0.5 moles of CO2 is

6.022 x 1023 x 0.50 = 3.011 x 1023.

Answer 2

Answer:  There are approximately 6.02 x 10^23 oxygen atoms in 0.50 moles of co2.

Explanation:

• Understanding the chemical formula of CO2 is necessary before we can estimate how many oxygen atoms are contained in 0.50 moles of CO2. One carbon atom and two oxygen atoms make up the compound CO2. As a result, there are two moles of oxygen atoms in every mole of carbon dioxide.

• By using the Avogadro's number, or around 6.02 x 1023 atoms/mol, we may determine how many oxygen atoms are present in 0.50 moles of carbon dioxide. The total amount of oxygen atoms may be calculated by multiplying the number of moles of CO2 by the Avogadro's number to obtain the number of molecules.

• 6.02 x 1023 atoms of O are produced by multiplying 0.50 mol CO2 by 6.02 x 1023 molecules/mol and 2 atoms of oxygen per mol.

• Because of the inherent uncertainty in experimental observations and the use of the Avogadro's number as a constant, the answer should be understood to be an approximation of the true number of oxygen atoms. Yet even so, this computation gives a reliable approximation of the number of oxygen atoms in the specified quantity of CO2.
