Question

What is the mass of a 5.00cm3 piece of copper having a density of 8.96g/cm3

Answer 1

44.8 grams

Step-by-step explanation:

The density exists as a ratio comparing the mass of a piece of copper per 1 cm³. Since you have been given a new volume, you can set up a proportion to find the new mass.

`(8.96 grams)/(1.00 cm^3) =(?grams)/(5.00cm^3)` <----- Proportion

`44.8 = (1.00cm^3)(?grams)` <----- Cross-multiply

`44.8= ?grams` <----- Divide both sides by 1.00
