What is mass of `C` obtained on reacting `20` moles of `A` with excess `B` by reaction
`{:(2A,+,B,rarr,3C):}`
If `%` yield of reaction is `80%` ? .

Explanation

`{:(2A,+,B,rarr,3C,),(20mol,,,,30mol="Theoreticalyield",),(,,,,"Actualyield=Xmol"=?,):}`
`rArr (X)/(30) xx 100 = 80 rArr X = 24"moles"` .
