Given the equation 2 CO + O2 - > 2CO2, how many grams of CO2 form if 34.0 grams of CO are combined with excess oxygen?

a) 53.4

b) 21.6

c) 145

d) 107

This question is really confusing to me, and I'm not even sure how to go about answering it.

    firstly we need to calculate the number of moles of 34.0 g CO.

    mole = mass/relative molecular mass = 34 / (12+16) = 1.214 mol

    CO : CO2 = 2 : 2 = 1 : 1

    so that number of moles of CO2 = number of moles of CO = 1.21 mol

    then use the number of moles to calculate the mass

    mass = mole * relative molecular mass = 1.21 * 44 = 53.4 g

    so choose A
