The density of copper with the values given in the question is #"300 g/cm"^3"#. This is NOT the correct density for copper, which is #"8.96 g/cm"^3"# near room temperature.

Explanation:

Density is the mass per unit of volume. The density equation is #"D="M/V"#, where #"D"# is density, #"M"# is mass, and #"V"# is volume.

The mass of copper is #"400 g"#. The volume is #"1.5 mL"#, which is equal to #"1.5 cm"^3"#. This is because #"1 mL"="1 cm"^3"#. Since copper is a solid, we'll use the cubic centimeter unit #("cm"^3")#.

Plug the values into the equation.

#"D"="400 g"/"1.5 cm"^3"##=##"300 g/cm"^3"# rounded to one significant figure.

NOTE!: The actual density of copper is #"8.96 g/cm"^3"#.
