Final answer:
The mass of a piece of copper with a volume of 10.4 mL and a density of 8.92 g/mL is 92.608 grams.
Step-by-step explanation:
The question is asking for the mass of a piece of copper with a volume of 10.4 mL. The density of copper is given as 8.92 g/mL.
To find the mass, we can use the formula:
Mass = Density x Volume
Substituting the given values:
Mass = 8.92 g/mL x 10.4 mL = 92.608 g
Therefore, the mass of the copper is 92.608 grams.
