How many number of oxygen molecules are required to produce 0.22 g of CO2 according to the reaction?
zmey [24]
The number of moles for co2=mass(g)/molar mass
n=.22/44=.005 mole of CO2
from the equation we see the relationship between the moles of co2 and O2 and we find that they have the same number of moles
So we need .005mole of O2
