To calculate the number of moles of solute in a solution, we use the formula:

moles = (concentration in mol/L) x (volume in L)

Firstly, we need to convert the volume from milliliters to liters:

400. mL = 0.400 L

Then, we substitute the given values into the formula:

moles = (0.200 mol/L) x (0.400 L) = 0.0800 mol

Therefore, the answer is A: 0.0800 moles.
