Question

2x+3y+4z= 5w initially if 1 mole of x 3 mole of y and 4 mole of z is taken and 1.25 mole of w is obtained then % yield of this reaction is

Answer 1

here x is the limiting reagent as it will be consumed completely.

1 mole of x supposed to give 2.5 moles of w.

but actual yield is 1.25 moles of w

There fore % yield = 1.25 x 100/2.5 = 50%
