Chemistry
1 answer:
erica [24]1 year ago
4 0

Answer:

Mass Percent of Pencils  =  7.20%

Explanation:

The mass percent can be calculated using the following equation. In this case, the "solute" is the pencil and the "solution" is the collection of pencils.

                               mass solute
Mass Percent  =  ------------------------  x 100%
                              mass solution

                                         9.540 g (pencil)
Mass Percent  =  --------------------------------------------  x 100%
                              132.456 g (pencil collection)

Mass Percent  =  7.20%
