When combined, aqueous solutions of sulfuric acid and potassium hydroxide react to form water and aqueous potassium sulfate according to the following equation (unbalanced): H 2 SO 4 ( a q ) + KOH ( a q ) → H 2 O ( l ) + K 2 SO 4 ( a q ) Determine what mass of water is produced when a beaker containing 100.0 g H 2 SO 4 dissolved in 250 mL water is added to a larger beaker containing 100.0 g KOH dissolved in 225 mL water. Determine the mass amounts of each substance (other than water) present in the large beaker when the reaction is complete.

please solve. If the answer is "no error" and it asks me to type something, and i typed a-helix, its always wrong.
Can you please solve and explain this for me in a simple way? I cant seem to comprehend this problem.
