FREE Expert Solution

Assume A = x and B = 5.8 - x

Moles of Z with A needed for the reaction is A = x

Moles of Z with B needed for the reaction is B = 2 (5.8-x)

Setting up the equation where 7.8 moles of Z is consumed:

Problem Details

A mixture of A and B contains a total of 5.8 mol. Both A and  B react with Z according to the following equations:

A + Z → AZ

B + 2Z → BZ2

The reaction of the mixture of A and B with  Z consumes 7.8 mol Z

Assuming the reactions go to completion, how many moles of  A does the mixture contain?

Express your answer in moles to two significant figures.
