Answer:
The answer is not 9.9 i used that and got it wrong
Explanation:
The molar mass of nitrogen is 14 bt since it is a nitrogen molecule (N2) the molar mass will be 14 x 2 = 28g/mol.
Step 1: Calculate the moles of N2
moles = mass / relative molecular mass
= 50g / 28g/mol
= 1.7857mol
Step 2: convert the moles of nitrogen into volume of N2
At STP the molar volume of a gas is 22.71L/mol
Hence the volume = 1.7857mol x 22.71L/mol
= 40.55L
50g if nitrogen (N2) has a volume of 40.55 liters at stp.
