Answer to Question #301613 in General Chemistry for hbjbjhjbhj

Question

Two hundred (200) grams of carbon is reacted completely with oxygen to form carbon dioxide. Calculate the volume of CO2 produced. The equation is: C(s) + O2(g) --> CO2(g) 

Answer 1

Moles of carbon = mass/MM = 200g/12gmol-1 = 16.67mol

Moles ratio of C : CO2 = 1:1

Moles if CO2 is therefore 16.67 mol

MGV = 24dm3 at r.t.p

Volume of CO2 = (16.67mol x 24dm3)/1mol

= 400.0 dm3
