wouldn't it be more than 1 g? i say this because the first substance that the oxygen would chemically combine to would have its own mass (1g), and once the oxygen combines to it, wouldn't the mass of the oxygen and the substance also combine, forming a new mass greater than 1 g?

What is the formula of the second compound if two oxides of a metal contain 27.6 percent and 30 percent of oxygen respectively and if the formula of the first compound is M3O4?
Formula of first oxide = M3O4 let mass of the metal be == x percentage of metal in M3O4 = (3x/ 3x+64) *100 but % age = (100-27.6) = 72.4 % so, (3x/ 3x+64)*100 = 72.4 or x = 56. in 2nd oxide, oxygen = 30%....so metal = 70% so, ratio :-- M : O 70/56 : 30/16 1.25 : 1.875 2 : 3 so, 2nd oxide = M2O3

A metal forms two oxidesThe higher oxide contains 80 percent metal 0.72g of lower oxide gave 0.8g of the higher oxide when oxidised Show that the data illustrates the law of multiple proportions?
In higher oxide Metal = 80% Oxygen = (100-80)% = 20% Therefore, we can say that 4 parts of metal combines with 1 part of oxygen. Now, 0.72 g of lower oxide on oxidation gives 0.8 g of higher oxide. It can be assumed that the mass percent of metal in 0.8 g is same as that of 0.72 g of lower oxide. So, Mass of metal in higher oxide = (80/100) x 0.8 g = 0.64 g If in 0.8 g of higher oxide 0.64 g is metal then mass of oxygen present in higher oxide will be (0.8 - 0.64) g = 0.16 g Since, lower oxide contains the same mass of metal as that of higher oxide, we need to calculate the mass of oxygen in lower oxide. Mass of oxygen in lower oxide = (0.72-0.64) g = 0.08 g According to Law to multiple proportions if two elements combine with each other to form two different compounds then the ratio of masses of that element which combines with the other element whose mass is fixed in both the compounds, will be in small whole numbers. Now, in the given problem the mass of metal in both the oxide is fixed so, for the data to illustrate the law of multiple proportion the ratio of mass of oxygen in both the oxides should be in whole numbers. Now, mass of oxygen in higher oxide : mass of oxygen in lower oxide = 0.16 : 0.08 = 2 : 1. Therefore, it can be said that the given data depicts law of multiple proportion.

In which of the oxides: manganese (IV) oxide or magnesia is a greater percentage by mass of non-metal, and in which there is a greater percentage by mass of metal. Give the formulas of both oxides, write down the calculations and the answer?
ammonium carbonate
What is the molar mass of oxide?
Depends on what oxide
Which of these alkaline earth metal oxides has the greatest percent by mass oxygen 1 barium oxide 2 beryllium oxide 3 calcium oxide 4 magnesium oxide 5 strontium?
2. beryllium oxide. Each oxide contains as many oxygen atoms as alkaline earth metal atoms, and beryllium has the smallest atomic weight of the alkaline earth metals. Therefore, beryllium oxygen has the greatest percentage by weight of oxygen.

Calculate the mass of Oxygen in the tin oxide
How and why does the mass of a magnesium strip change when it is heated strongly in air?
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
What is the mass of lithium oxide made from 20g of lithium carbonate?
The mass of lithium oxide (Li2O) is 8,o9 g.
