What is the volume at one atmosphere of one kilo of nitrous oxide in cubic metres
+37146 Nitrous oxide is N2O Molecular weight is 14(2) + 16 = 44 gm/mole
STP = Standard Temp and Pressure 0 degrees C and one atm pressure
One mole of gas occupies 22.4 liters of space at STP
1kg of N2O is 1000/44 moles = 22.727 moles
22.727 moles x 22.4 l / mole = 509 liters A cubic meter is 1000 liters 509/1000= .509 m^3 for 1 kg N20 @ STP (about a half of a cubic meter)
