5.0 g of hydrocarbon gas formula C2H4 has a volume of 1.3 L at 1.05 atm. The temperature of the gas is
Given mass of hydrocarbon C2H4 is 5.0 g Given volume of hydrocarbon is 1.3 L and pressure is 1.05 atm.
Molar mass of C2H4 is 28 g/mol
We have to calculate the temperature of the hydrocarbon.
Convert 5.0g C2H4 to corresponding mole:-
5.0g C2H4 =5.0g C2H4 ×
Recall the ideal gas equation
Calculate temperature by substituting values in ideal gas equation
Therefore , temperature of gas is 92.9K
Therefore the temperature in celsius scale is = (92.9-273) °C
= -180.1 °C
Hence temperature of the gas is -180.1°C
