Final answer:
The density of N2O gas at STP can be calculated using the ideal gas law equation.
Step-by-step explanation:
The density of N2O gas at STP can be calculated using the ideal gas law equation. The ideal gas law equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. At STP, the pressure is 1 atm and the temperature is 273 K. Since we want to find the density, we can rearrange the equation to solve for density: density = n/ V.
To find the number of moles, we can use the molar mass of N2O, which is 44.01 g/mol. The number of moles is equal to the mass divided by the molar mass: n = mass/ molar mass. Finally, we can substitute the values into the equation and calculate the density of N2O gas at STP.
