38 an aluminum sample has a mass of 80.01 g and a density of 2.70 g/cm3. according to the data, to what number of significant figures should the calculated volume of the aluminum sample be expressed? (1) 1 (3) 3
(2) 2 (4) 4

19. at high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why? eman- it is much less because real gas partides are not moving. there is no difference because the gas laws are always obeyed. it is much less because at high pressures the temperature drops. it is much greater because real gas partides take up space.
