Question

1. You have 6 moles of a 2 M solution. How many Liters are present?

Answer 1

We are given the moles and molarity of the solution. To find the liters we must take into account the definition of molarity. Molarity is defined as:

$Molarity=\frac{MolesSolute}{Lsolution}$

We clear the liters of the solution and replace the known data:

$\begin{gathered} Lsolution=\frac{MolesSolute}{Molarity} \\ Lsolution=\frac{6mol}{2M}=\frac{6mol}{2mol/L}=3L \end{gathered}$

Answer: There are present 3 liters
