44 a 25.0-g sample of each of three unknown metals is added to 25.0 ml of water in graduated cylinders a, b, and c, and the final volumes are depicted in the circles below. given their densities, identify the metal in each cylinder: zinc (7.14 g/ml), iron (7.87 g/ml), or nickel (8.91 g/ml).

Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL

Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL

Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL

Calculate grams/mL (density)

A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc

Hope I helped!

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml
