Calcium hydroxide (“slaked lime”) and sulfuric acid react to produce calcium sulfate and water according to the following balanced equation: Ca(OH)2 (aq) + H2SO4 (aq) -> CaSO4 (s) + 2 H2O (l)

Our H2SO4 solution is 0.5 M and we end up titrating (adding) 50 mL to an excess amount of Ca(OH)2 in H2O. Using the molarity and volume, how much CaSO4 do we end up producing in grams?

SKSKSKSK Thnx for the points

The answer is c. 320 g

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
