Can some one help me in few questions related to my studies?

Since 2moles of o2 react with 1mole ch4 i.e 2*32gm=64gm o2 reacts with 1*12gm of ch4(molar m of o2=32gm,of ch4=16gm i.e 12gm for c and 4gm of 4 h atoms) nw according to reaction 64gm o2 reacts with 16gm ch4..for reaction with 24gm ch4 we need 64/16 *24gm=96gm o2
