In order to find the number of particles of 88 grams of CO2, we need to find the number of moles, using its molar mass, 44g/mol:
44g = 1 mol
88g = x moles
x = 2 moles of CO2 in 88 grams
Now that we have the number of moles, we can find the number of particles, using the Avogadros constant umber, whic h is 6.02*10^23 atoms or particlesfor each mol:
6.02*10^23 particles = 1 mol
x particles = 2 moles
x = 1.2*10^24 particles in 88 grams of CO2, letter B
