Hello!
How many moles of each substance are contained in 88g of carbon dioxide?
Since it's CO2:
Ar of carbon= 12
Ar of oxgen = 16
Mr of Carbon dioxide = 44
88g/44= 2 Mol of CO2 formula units
Since the ratio is 1:2 carbon to oxygen:
(88/3)/12=22/9 Mol of Carbon
(i.e. 1/3 of 88g is how many grams carbon represents?)
and
(176/3)/16=11/3 Mol of oxygen
(i.e. 2/3 of 88g is how many grams oxygen represents)
Is this right? Any replies much appreciated! Thanks in advance!
