Magnesium to oxygen and the empirical formula of magnesium oxide from the class data notebook template: your lab notebook should include the masses of (1) the empty crucible, (2) the crucible with. In relation to our lab, the law of definite composition states that we should have the same ratio of magnesium to oxygen in magnesium oxide this will always be 1 to 1, because the formula for magnesium oxide is mgo.
Law constant composition lab magnesium and oxygen
We can not easily weigh the amount of oxygen gas used to combust the magnesium, but we don't have to because we can use the law of mass conservation to calculate how much oxygen is present in the magnesium oxide we produce:. The purpose of this lab was to find “r” we took magnesium reacted it with hydrochloride acid and collected the gas the results of this lab should have been finding the gas constant “r” which is 08206(atm x l)/(mol x k). The law of constant composition states that atoms combine in proportions to form compounds, % magnesium magnesium magnesium oxide % oxygen magnesium oxide lab. Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition taking just one atom of mg and one atom of o you will get a mass of 160 + 243 = 403 for the unit that represents the minimum amount of magnesium oxide.
