Question

A gem has a mass of 5.50 g. When the gem is placed in a graduated cylinder containing 9.000 mL of water, the water level rises to 11.45 mL.
Express the density in grams per milliliter to three significant figures.

Answer 1

D = M x V

M = 5.50

V = 11.45 - 9.00 = 2.45

D = 5.50 x 2.45

D = 13.475
