Question

How many moles of glucose (C6H12O6) are in 5.0 liters of a 2.5 M C6H12O6 solution?

a) 2.0 moles

b) 2.5 moles

c) 7.5 moles

d) 13 moles

2 Answer

  • 5*2.5 = 12.5 ≈ 13 moles
  • Answer:The correct answer is option d.

    Explanation:

    Molarity of the solution = 2.5 M =2.5 mol/L

    Number of moles of glucose = n

    Molarity is defined as ratio of moles of solute to the volume of the solutions in liters.

    [tex]Molarity=\frac{\text{Moles of}C_{6}H_{12}O_6}{\tex{Volume of the solution(L)}}[/tex]

    [tex]2.5 mol/L=\frac{n}{5.0L}[/tex]

    [tex]n=12.5 moles[/tex]

    The closest option to our answer is option d.

    Hence,correct answer is option d.
