Question

How many atoms of oxygen are present in the reactants
6CO2+6H2O=C6H12O6+6O2

Answer 1

There are 18 oxygen atoms in the reactants of the chemical equation 6CO2 + 6H2O = C6H12O6 + 6O2.

Step-by-step explanation:

The student has asked how many atoms of oxygen are present in the reactants of the following chemical equation:

6CO2 + 6H2O = C6H12O6 + 6O2

To find out the total number of oxygen atoms in the reactants, we count the oxygen atoms in each molecule and multiply by the coefficients. In 6 molecules of CO2, there are 2 oxygen atoms each for a total of 6 x 2 = 12 oxygen atoms. In 6 molecules of H2O, there is 1 oxygen atom each, contributing another 6 oxygen atoms. Adding these together, 12 + 6 oxygen atoms gives us a total of 18 oxygen atoms in the reactants.

Answer 2

3.6132 * 10^24 atoms/molecules of 02

Step-by-step explanation:

When we look at the balanced chemical equation, we can see that there are 6 moles of O2.

In order to convert from moles to formula units (atoms and molecules),

you need to multiply by avogadro's number.

6 moles *
`6.022*10^(23)`/1 mol = 3.6132 * 10^24 atoms/molecules of 02
