Standard Temperature and Pressure (STP) is defined as a temperature of 0.00oC and a pressure of 100kPa. If the molar mass M of nitrogen is 14.0 g/mol, find the density (kg/m3) of nitrogen gas (N2) at STP. Nitrous Oxide or laughing gas is composed of the molecule N2O. If the molar mass of oxygen is 16.0g/mol, what is the density of N2O at STP?
