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:
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.
