Can someone eplain how to do this ? : identify the limiting reagent and the volume of co2 formed when 11 l cs2 reacts with 18 l o2 to produce so2 gas at stp. cs2(g)+3o2(g) → co2(g)+2so2(g),

Te limiting reagent from CS2 (g) + 3O2(g)>CO2(g) +2SO2(g) is O2. It is defined as the substance that is totally consumed when the chemical reaction is complete. The excess reagent is CS2.

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.
