** Calculate the density of mercury if 1.00 x 102 g occupies a volume of 7.36 cm3.
Density = mass = 1.00 x 102 g = 13.6 g/cm3
volume 7.36 cm3
(214= THREE significant figures)
(1004 = FOUR significant figures)
(0.01 = ONE significant figure)
(4.0 = TWO significant figures)
*Converting 8.00 meters to inches
8.00 m x 100 cm x 1 in. = 315 inches
1 m 2.54 cm
