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.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
How many oxygen molecules can be made from 52.8 grams of water?
The formula of water is H2O and that of oxygen molecules is O2. The fraction by mass of oxygen in water is the atomic mass of oxygen divided by the molecular mass of water, which in turn is the sum of the atomic mass of oxygen and twice the atomic mass of hydrogen, or {15.999/[15.999 + 2(1.008)]} = 0.888, to sufficient significant digits to correspond to the problem information of 52.8 grams of water. The mass of oxygen in this amount of water therefore is 0.888 X 52.8 = 46.9 grams. The molecular mass of oxygen atoms is 2 X 15.999 = 32.0, so that 46.9 grams corresponds to 46.9/32.0 = 1.466 moles of oxygen molecules. The number of molecules per mole of any substance is Avogadro's number, 6.022 X 1023. The answer to the problem is this number multiplied by the number of moles = 1.466 X 6.022 X 1023 = 8.83 X 1023.
What is the difference between mass and water?
Mass is a unit of measurement and water is a substance. Namely a combination of hydrogen and oxygen in a 2 to 1 ratio.
What is the difference between atomic mass an molecular mass?
Atomic mass is defined for atoms. Molecular mass is defined for molecules or compounds. Atoms bond with each other to form compounds.
What is the difference between atoms oxygen 16 and oxygen 17?
The main difference between oxygen-16 and oxygen-17 is their atomic mass. Oxygen-16 has 8 protons and 8 neutrons, while oxygen-17 has 8 protons and 9 neutrons. This difference in neutron number results in oxygen-17 being slightly heavier than oxygen-16.
What is the difference between measuring mass and weight?
Mass is the amount of matter or molecules that a specific object is composed of. Weight is the measure of gravity's pull on you. Does this help answer your question?
Why hydrogen in water is heavier than pure hydrogen?
To clear up any confusion: water is not a mixture of hydrogen and oxygen; it is a compound. The hydrogen and oxygen are chemically bonded to each other to form a completely different substance. There are two reasons for the difference in density. First, molecules of elemental hydrogen are only weakly attracted to one another, so hydrogen exists as a gas with a lot of space between molecules. Water molecules are very strongly attracted to one another and so water exists as a liquid with much less space between molecules. Second, a water molecule contains two hydrogen atoms and one oxygen atom. One oxygen atom has about 16 times the mass of a hydrogen atom, so most of the mass of water is actually oxygen. One water molecule is about 9 times the mass of a hydrogen molecule.
Do air molecules have mass?
Yes, air molecules do have mass. Air is made up of various gases such as nitrogen, oxygen, and carbon dioxide, and each of these gas molecules contributes to the overall mass of the air.
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.
What is affected by the mass of molecules that make up the material and the distance between them?
The density of the material is affected by the mass of molecules and the distance between them. If the molecules have higher mass and are closer together, the material will have higher density.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
What mass of oxygen contain same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
Why does water have more mass than oil?
Water has more mass than oil because water molecules are more tightly packed together and have a greater density than oil molecules. This means that the same volume of water will contain more mass compared to the same volume of oil. This is due to differences in molecular structure and composition between water and oil molecules.
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
