How many covalent bonds are present in 9g of H2O?
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.
What is the percentage of oxygen by mass in water?
The percentage of oxygen by mass in water is approximately 88.8%.
What is the mass of the table salt if the combined mass of the table salt and the container is 124g and the mass of the container is 9g?
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.
If you heat 10g wood and produce 1g of ash what is the mass of other products produced?
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.
How does combining hydrogen and oxygen to create water relate to the law of conservation of mass?
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.
Which one has more molecules in 9g of water or 9g of sugur?
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.

What is an example of the law of constant composition?
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 carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
How one has more molecules 9g of water or9g of sugar?
Perhaps you mean: Does sugar have more atoms than water?In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular mass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance.We rearrange this to form Number of moles = Mass / Molecular massTherefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law:1 mole = 6 * 10^23 molecules (constant value)However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether.I hope this was helpful! :)
What is 9g-g?
9g+9
What is the mass difference between water and hydrogen plus oxygen?
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.
If 9.0g of water contain 1.0g of hydrogen what mass of oxygen is contained in 36g of water?
What an odd question. Well, whatever. The question shows that 1/9 of the solution is hydrogen. So it must be said that 8/9 is water (assuming the sample comprises solely of hydrogen and water)36/9 = 44 x 8 = 32So 32g of it is oxygen.
Does the mass of oxygen required equal the mass of the water formed?
Nope. :D
