For this problem, we’re being asked to determine the number of N2O4 molecules found in 76.3 g CO2. The flow for this problem will be like this:
Mass of N2O4 (molar mass of N2O4) → Moles of N2O4 (Avogadro’s number) → Molecules of N2O4
How many molecules of N2O4 are in 76.3 g N2O4? The molar mass of N2O4 is 92.02 g/mol.
a. 5.54 x 1025 N2O4 molecules
b. 4.99 x 1023 N2O4 molecules
c. 4.59 x 1025 N2O4 molecules
d. 1.38 x 1024 N2O4 molecules
e. 7.26 x 1023 N2O4 molecules
