Answer:
42 grams
Step-by-step explanation:
the conversion between moles and grams is by using the molar mass of the substance.
The molar mass for a nitrogen atom is 14.00 g/mol.
N2 has two nitrogen atoms, so its molar mass is 28.00 g/mol
To find how many grams are in 1.5 moles;
the units of mols cancels out, leaving one with units of grams of N2
