Final answer:
The density of metal B can be calculated using the formula D = M/V. Determine the correct density by comparing the calculated density with the given options.
Step-by-step explanation:
The density of metal B can be calculated using the formula D = M/V, where D is the density, M is the mass, and V is the volume.
Given the options for the density of metal B are 4.0 g/cm³, 2.0 g/cm³, 8.0 g/cm³, and 10.0 g/cm³, we can determine the correct density by comparing the calculated density with the given options.
For example, if the mass of metal B is 8 grams and the volume is 2 cm³, then the density would be 4 grams per cubic centimeter (g/cm³), matching the first option.
