1. ### osmium has a density of 22.6 g/cm 3. the mass of a block that measures 1.01 cm x 0.233 cmx0.648 cm?

(volume, cm 3) = (1.01 cm)*(0.233 cm)*(0.648 cm) (volume, cm 3) = .152494 cm 3 Density = (grams)/(volume, cm 3, ml) grams = (density)*(volume, cm 3, ml) mass = (22.6 g/cm 3) * (.152494 cm 3) mass = 3.45 grams
