Respuesta :
The 1.5 g of [tex]N_{2}[/tex] would occupy more volume at a constant temperature and pressure .
Calculation ,
So, to find volume occupy by the 1.5 g of nitrogen gas or 1.5 g of oxygen gas we have to calculate number of moles of each first .
Number of moles of nitrogen gas = given mass/molar mass = 1.5 g/14 g/mol
Number of moles of nitrogen = 0.107 mole
Number of moles of oxygen gas = given mass/molar mass = 1.5 g/16 g/mol
Number of moles of oxygen gas = 0.093 mole
According to ideal gas equation,
PV = nRT
Where , P is pressure of the gas
V is volume of the gas
n is number of moles of the gas
R is gas constant of the gas
T is temperature of the gas
According to ideal gas equation, at constant temperature and pressure the volume is directly proportional to the number of moles of the gas .
So , number of moles of nitrogen is greater than oxygen .
Therefore , nitrogen gas would occupy more volume at a constant temperature and pressure.
