The density of dry air is 1.12X10-3G/CM3 WHAT VOLUME OF AIR IN CUBIC METERS WILL HAVE A MASS OF 100KG

Answer 1

oobleck worked this problem for 1.00 kg (not 100 kg) and I have copied his solution here.
"(a) mass = density*volume, so
1.00 g = 1.12*10^-3 v
v = 0.8928g * 10^3 cm^3 * 1kg/1000g * (1m/100cm)^3
= 0.8928 * 10^-6 m^3
