Assignment Help Chemistry
Reference no: EM13560023

One mole (Avogradro's number of particles) of any gas at standard temperature (0 degrees C) and pressure (1 atmosphere) occupies a volume of 22.4L. Note that Avogadro's number is 6.022 x 10^23; 1L = 103 cm3. If the density of air is 1.2 kg/m3, what is the weight of one mole of air in scientific notation and appropriate units?
