Final answer:

The mass of the copper bar is calculated by multiplying its density (9g/cm³) by its volume (26 cm³), resulting in a mass of 234 grams.

Step-by-step explanation:

The mass of any object can be found using the formula for density, which is mass divided by volume. Given that the density of copper is 9g/cm³ and the volume of the copper bar is 26 cm³, we can calculate the mass as follows:

Mass = Density × Volume

Mass = 9g/cm³ × 26 cm³

Mass = 234g

Therefore, the mass of the copper bar is 234 grams.
