How many moles in 14 grams of N2

Answer 1

To calculate the number of moles in 14 grams of N2, you first need to determine the molar mass of nitrogen gas (N2).

The molar mass of N2 is 14.01 g/mol (from the periodic table).

Now, you can use the formula:

moles = mass / molar mass

moles = 14 g / 28.02 g/mol
moles = 0.5 moles

Therefore, there are 0.5 moles of N2 in 14 grams of nitrogen gas.
