The moles of B that will be needed to convert 2 moles of A into as many moles of C as possible is 6 moles

Explanation

3A +9B → 5C

The moles of B are calculated using the mole ratio.

That is; from the equation above the mole ratio of A:B is 3:9

If the moles of A required is 2 moles therefore the moles of B

= 2 x9/3= 6 moles
