This question can be explained in a variety of ways, but the easiest can be that elements exist, and since each has a different atomic mass, all atoms are not identical in size and mass.
The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.
44.009 grams of CO2 = 1 mole of CO2 CO2 = Carbon dioxide
25 ÷ 44.009 ≈ 0.568
About 0.568 moles of CO2

The percent abundance in the container by bean will be 43.33 % if there are 10 navy beans, 3 pinto beans, and 17 lentils in a container
<h3>What is Percentage composition ?</h3>
The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100.
% composition by bean = number of beans / total number of objects in container x 100
- Total object = 10 ( navy beans) + 3 (pinto beans) + 17 ( lentils) = 30 objects
- Total beans = 10 ( navy beans) + 3 (pinto beans) = 13 beans
hence ;
- % composition by beans = 13/30 x 100 = 43.33 %
Therefore, the percent composition of the container by bean is 43.33 %
