(1) Calculate the i) mass and ii) volume at r.t.p of oxygen gas required to convert 6g of carbon to carbon (IV) oxide. (C=12, O=16) molar gas volume at r.t.p = 24dm
Step I
2 Write the stoichiometric equation for the reaction.
C(s)+O2g)→CO2(g)
Step II
Write down the mole ratio for each of the substance
C(s) + O2g)→CO2(g)
1 mole 1 mole 1 mole
Step III
Work out the RMM of the oxygen gas RAM of oxygen gas
O =
    
2 x O = 2 x
=
    
RAM of C=
