Answer:

1.6moles

Explanations:

The formula for calculating the molarity of a solution is expressed according to the equation:

[tex]molarity=\frac{moles}{volume}[/tex]

Given the following parameters

volume of solution = 400mL = 0.4L

molarity of the solution = 4M

Determine the moles present

[tex]\begin{gathered} moles=molarity\times volume \\ moles=\frac{4mol}{L}\times0.4L \\ moles=1.6moles \end{gathered}[/tex]

Hence the number of moles present is 1.6moles
