A student was provided with a solid sample made up of a mixture of components. Prior to separation, the student measured 2.895 g of the mixture. After separation, the student found the mixture contained the following four components: Component 1: 1.12g
Component 2: 0.756g
Component 3: 0.254g
Component 4: 0.525g

Which component has the highest mass % for the mixture?

Component 1, since it has the greatest mass.

Explanation:

Hello,

In this case, considering that the by-mass percent of a substance is computed:

In such a way, given the form of the equation one could infer that the higher the mass of the i component, the higher its by-mass percent, it means that the component with the greatest mass will have the highest by-mass percent for the mixture. In such a way, since the component 1 was found to have a mass of 1.12 g, it will have the highest by-mass percent.

Best regards.

it's c. elements are placed in rows based on how may valencies electrons have.

lol for the pointsss
