Dry sand has a density of 1.5 g cm-3. A child's sandbox, measuring 4.0 by 5.0 ft, is filled with sand to a depth of 6.0 in. What is the mass of the sand in kg? in lb?
Homework Answers
Volume = l x b x h
l = 4 ft = 121.92 cm
b = 5 ft = 152.4 cm
h = 6 in = 15.24 cm
Volume of sandbox = 121.92 x 152.4 x 15.24 = 283168.47 cm^3
Mass of sand = density x volume = 1.5 g/cm^3 x 283168.47 cm^3 = 424752.7 g
= 424.753 kg
= 936.419 lb

3. The volume of blood plasma in an adult is 5.0 L, about 95% of which is water, and it has a density of 1.025 g/mL. The pressure at an underwater depth of 30.0 m is 4.1 atm (4.154325 bar). If a SCUBA diver descends to this depth, how many mg of N, (KH=6.0 x 10 mol/kg*bar) are dissolved in her blood? What percentage of N, comes out of the solution when the diver surfaces (at sea level)? Assume constant...

3) During an environmental assessment of a natural wetland in the Everglades, it was determined that 1.5 cubic meters of the dry native soil had a mass of 420 kg. Determine the mass of a cubic foot of the same soil. Hint: calculate the density of the soil and then use the density to calculate the mass associated with 1 ft of the Everglades soil. (mass = 7.9 kg or 17.38 lbm or 0.54 slug) 4) A research has added...
