Answer:

0.0022 concentration

Explanation:

concentration = moles of solute / liters of solution

first off, convert 125g of potassium sulfate into moles. we can do this using conversion factors. the conversion factor we will use is potassium sulfate's molar mass.

125g K2SO4 * ( 1 mol / 174.259) = 0.720 moles potassium sulfate

then, we follow the concentration formula

0.720 moles potassium sulfate / 325.6 L = 0.0022 concentration
