Question

The balanced equation C + O2→CO2 tells us that 24.02 g of carbon will exactly react with
a) 32.0 g of O2
b) 2.0 moles of O2
c) 6.02 E 23 molecules of O2
d) no correct response

Answer 1

ok so amount of C is:
n=24,02 g / 12,011 gmol-1 = 2 mol
so i would say answer is B) because
m= 2 mol * 32 gmol-1 = 64 g

Answer 2

moles of carbon is 2....(24.02 / 12.01)
2moles of c will react with 2 moles of oxygen...
thus ,option is B

Answer 3

Thank you so very much!
