Answer
53.47 grams
Step-by-step explanation
to calculate the mass (grams) of the nitrogen, we first need to determine the number of moles
1 mole has 6.022x10^23 molecules according to Avogadros number
to get the number of moles we divide 2.3x10^24 by avogadros number
(2.3x10^24) / (6.022x10^23)
= 3.819 moles
the mass can be determine by using the following equation
mass = n x M
n - moles
M - Molar mass of nitrogen
mass = (3.819 mols) x (14.00g/mol)
= 53.47 grams
