Molar mass N₂ = 28.0 g/mol
Number of moles:
n = mass / molar mass
n = 14 / 28.0
n = 0.5 moles
1 mole N₂ -------- 22,4 ( at STP)
0.5 mole N₂ ------- ?? Liters
L = 22.4 * 0.5 = 11,2 L
hope this helps!
The enthalpy of combustion of propane is -2202.0 kJ/mol.
The enthalpy of combustion is released when one mole of compound is burned in the presence of excess oxygen. The bonds between carbon and hydrogen in the compound are broken and bonds between carbon and oxygen are formed as well as bonds between hydrogen and oxygen are formed.
