ANSWER

4A+2B+3C⟶A

4

B

2

C

From the reaction-

No. of moles of element B required to react with 4 moles of element A =2

No. of moles of element B required to react with 2 moles of element A =

4

2

×2=1 mole

Given amount of element B = 1.2 moles

No. of moles of element C required to react with 4 moles of element A =3

No. of moles of element C required to react with 2 moles of element A =

4

3

×2=1.5 moles

Given amount of element C = 1.44 moles

∴ In the given reaction, C is limiting reagent.

Therefore,

No. of moles of product formed when 3 moles of element C react =1 mole

No. of moles of product formed when 1.44 moles of element C react =

3

×1.44=0.48 moles

Hence, 0.48 moles product formed
