90/180.1559
=0.4995
0.4995*22.4
A.
=11.2
Is this correct
No. mols glucose is right.
You didn't convert mols glucose to mols CO2; i.e., you left out the step before the x 22.4
Is the answer right
11.2
Of course not. If you didn't convert mols glucose to mols CO2 it can't be right.
To check the correctness of the calculation, let's go through the steps:
1. 90/180.1559 = 0.4995 (this division is correct).
2. 0.4995 * 22.4 = 11.1948 (this is the actual result of the multiplication, not 11.2).
So the correct answer to the calculation 0.4995 * 22.4 is 11.1948, not 11.2.
