In 9g of H2O, there are approximately 3.01 x 10^23 molecules of water. Each water molecule contains 2 covalent bonds - one between the oxygen and each of the hydrogen atoms. So, there are a total of 6.02 x 10^23 covalent bonds present in 9g of H2O.
The percentage of oxygen by mass in water is approximately 88.8%.
The mass of the table salt can be calculated by subtracting the mass of the container from the combined mass of the table salt and the container. So, 124g - 9g = 115g. Therefore, the mass of the table salt is 115g.
Given that wood is primarily composed of carbon, hydrogen, and oxygen, upon combustion, the remaining products are typically carbon dioxide and water vapor. If 10g of wood produces 1g of ash, the remaining products would weigh approximately 8-9g.
When hydrogen and oxygen combine to form water, the total mass of the reactants before the reaction is equal to the total mass of the products after the reaction. This demonstrates the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
There are more molecules in 9g of water than in 9g of sugar. This is because the molecular weight of water is lower than that of sugar, so there are more water molecules present in the same mass as sugar.

A compound always contains the same elements in the same proportions by mass. This is a formal way of saying that a compound always has the same formula, no matter how it is made or where it is found.
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
9g of sugar would have more molecules than 9g of water because sugar molecules are larger and heavier than water molecules. This means that for the same weight, there would be fewer sugar molecules compared to water molecules.
The mass of water would be equal to the mass of oxygen plus the mass of hydrogen used in the reaction. The law of the conversation of mass states that in a reaction no mass is either gained or lost. In this case the total amount of mass of the reactants (Oxygen and Hydrogen), according to the law of the conversation of mass, must be equal to the product (water), because no mass can be lost or gained during the reaction.
9g+9
Since water is made of two hydrogen atoms and one oxygen atom, to find the mass of oxygen in 36g of water, you first need to find the total mass of hydrogen in 36g of water. Once you have that, you can subtract that mass from the total mass of water to find the mass of oxygen.
Nope. :D
