Question

How many moles of glucose (C6H12O6) are in 4.0 liters of a 4.5 M C6H12O6 solution?

18 moles

12.5 moles

8.5 moles

1.1 moles

Answer 1

Molarity (M) is defined as\[M = {{\rm moles~ of~ solute} \over {\rm liters~ of~ solution}}\]Let's set-up the equation with the known values. \[4.5 = {n \over 4.0}\]
