Question

How many moles of carbon (C) are in 1.22 moles of C6H12O6?

A) 1.22
B) 6.1
C) 7.32
D) 12.2

Answer 1

To calculate the moles of carbon in 1.22 moles of C6H12O6, multiply 1.22 by 6, the number of carbon atoms in the glucose molecule, yielding 7.32 moles of carbon.

Step-by-step explanation:

To determine how many moles of carbon (C) are in 1.22 moles of C6H12O6, we look at the molecular formula C6H12O6, which indicates that each molecule contains 6 moles of carbon. If we have 1.22 moles of C6H12O6, we will multiply this amount by the number of moles of carbon present in one mole of C6H12O6:

Number of moles of carbon = Moles of C6H12O6 × Moles of carbon per mole of C6H12O6

= 1.22 moles of C6H12O6 × 6 moles of C per mole of C6H12O6

= 7.32 moles of C.

Therefore, the correct answer is C) 7.32.
