2. ### What s the radius of a cylinder that is 1.80 cm long and has a mass of 13.4 g . For a cylinder, V=πr2l. (The density is 2.70 g/cm3.)?

V = mass / density = 4.9630 cm^3 r^2 = V/(πl) = 0.8776 --->r =0.94 cm

8. ### One cubic centimeters (1.0 cm^3) of mercury has a mass of 0.014 kg at 25 degrees C , find the mass of 3.5m^3 of mercury at 25 degrees C?

1 cubic meter = 10^6 cubic cm 0.014 kg/cm^3 * 3.5 * 10^6 cm^3 => 3.5 * 0.014 * 10^6 kg => 3.5 * 1.4 * 10^(-2) * 10^(6) kg => 3.5 * 1.4 * 10^(4) kg => (7/2) * (7/5) * 10^4 kg => (49/10) * 10^4 kg => 4.9 * 10^4 kg 49000 kg
