One container contains 4 moles of carbon dioxide. Calculate: 1) The number of carbon dioxide molecules? 2)The number of carbon atoms ? 3) The number of oxygen atoms?

1. 2.408 x 10²⁴ molecules

2. 2.408 x 10²⁴ atoms

3. 4.816 x 10²⁴ atoms

Given

4 moles of Carbon dioxide.

Required

Carbon dioxide molecules

Carbon atoms

Oxygen atoms?

Solution

1 moles = 6.02 x 10²³ particles(molecules, atoms, ions)

1. Carbon dioxide molecules :

= 4 moles x 6.02 x 10²³

= 2.408 x 10²⁴ molecules

2. The number of Carbon atoms

In CO₂, there is 1 atom C, so the number of atoms :

= 1 x 2.408 x 10²⁴

= 2.408 x 10²⁴ atoms

3. The number of Oxygen atoms :

In CO₂, there is 2 atom O, so the number of atoms :

= 2 x 2.408 x 10²⁴

= 4.816 x 10²⁴ atoms

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
