A student is given separate samples of three substances A, B, and C, along with a graduated cylinder containing 50.0mL of water.  Each sample has a mass of 200.0g, and the student finds that the volumes of the samples in the water are:

Element  Density(g/mL
Gold 19.8
Lead 11.4
Iron 7.8
Aluminium 2.7

A = 75.64mL B = 60.36mL C = 67.54mL

a. A= lead, B = Iron, C = aluminum

b. A = Iron, B = gotd, C = lead

c. A = gold B = iron, C = lead

d. A = atuminum B = gold, C =Iron

e. These substances are not any of the substances given.
