For the following hypothetical reaction:
olga55 [171]

 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
