Answer:
2.3531 cm³ Cu
Step-by-step explanation:
To find the volume of the copper, you need to multiply the given mass (g) by the density. You can use the denisty to convert between g and cm³ because denisty is a ratio that represents the mass of copper per every 1 cm³. It is important to arrange this ratio in a way that allows for the cancellation of units (grams should be in the denominator to cancel the units of the given mass). The final answer should have 5 sig figs like the given mass (21.084 = 5 sig figs).
Density = 8.96 g/cm³
21.084 g Cu 1 cm³
