A metal block has a mass of 5 grams and a volume of 1 cubic centimeter. A piece of the same kind of metal with a volume of 2 cubic centimeters has a density of A)2.5 g/cm³. B)5 g/cm³. C)10 g/cm³.

Question

Quizplus · Accepted Answer

Density = mass/volume. For the first metal block, density = 5g/1cm³ = 5 g/cm³. For the second piece, density = mass/volume = mass/2cm³. Since the metal is the same, the mass is the same, so density = 5g/2cm³ = 2.5 g/cm³. Therefore, the best choice is B, which is 5 g/cm³ for the first metal block and 2.5 g/cm³ for the second piece with a volume of 2 cm³.
