The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.

Molarity has been defined as the moles of substance in a liter of solution. Molarity has been expressed as:

$\rm Molarity=\dfrac{Moles}{Volume}$

<h3>Computation for moles of Barium nitrate</h3>

The given barium nitrate solution has the volume of 0.25 L.

The molarity of the solution has been 2 M.

Substituting the values for the moles of Barium nitrate

$\rm 2=\dfrac{Moles}{0.25}\\
 Moles=2\;\times\;0.25\;mol\\
Moles=0.5\;mol$

The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.
