How many atoms of nitrogen are in 1.2 grams of aspartame?

The molecular formula for aspartame is C14H18N2O5, and its molar mass is about 294 g/mol.

Convert 1.2 g into moles, which gives

1.2 g / 294 g/mol = 4.08 X 10-3 moles aspartame.

Since each mole of aspartame has 2 moles of nitrogen, you have 8.16 X 10-3 moles of N in your 1.2 grams of aspartame.

Finally, multiply that by Avogadro's number to get the number of N atoms:

8.16 X 10^-3 mol X 6.02 X 10^23 = 4.9 X 10^21 nitrogen atoms.

False because saturated fatty acids contain only single bond
