If there are 10 navy beans,3 pinto beans,and 17 lentils in a container,what is the percent composition of the container by bean?

Stells [14]

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 %
