What is the relative molecular mass of caco3?
The relative molecular mass of CaCO3 (calcium carbonate) is approximately 100.09 g/mol.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
What is molecular mass?
Molecular mass is the sum of the atomic masses of all the atoms in a molecule. It is usually expressed in atomic mass units (amu) or grams per mole (g/mol). Molecular mass is used to determine the mass of a substance in chemical reactions and stoichiometry calculations.
Why does h2o have a lower relative molecular mass than cs2?
H₂O (water) has a lower relative molecular mass than CS₂ (carbon disulfide) because the molecular mass of H₂O is approximately 18 g/mol (composed of two hydrogen atoms and one oxygen atom), while CS₂ has a molecular mass of about 76 g/mol (comprising one carbon atom and two sulfur atoms). The difference in the number and mass of the constituent atoms results in H₂O having a significantly lower molecular weight compared to CS₂.

What is the symbol Mr used for in chemistry?
The symbol Mr in chemistry stands for the relative molecular mass of a compound. It represents the average mass of a molecule of the compound compared to one-twelfth of the mass of an atom of carbon-12.

H₂O (water) has a lower relative molecular mass than CS₂ (carbon disulfide) because the molecular mass of H₂O is approximately 18 g/mol (composed of two hydrogen atoms and one oxygen atom), while CS₂ has a molecular mass of about 76 g/mol (comprising one carbon atom and two sulfur atoms). The difference in the number and mass of the constituent atoms results in H₂O having a significantly lower molecular weight compared to CS₂.
Why do relative molecular mass have decimals?
They are the calculated averages of all the isotopes of a particular element in accordance to their relative abundances, and hence is generally not an integer due to the mathematical division involved.
How do you convert from molecular mass to grams per mole?
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
What is RMM?
RMM is Relative Molecular Mass. e.g. water: 1 mole of water = 18g It is the mass of all the atoms in the molecule added up. The mass of hydrogen is 1 and oxygen is 16 Water is H20 so there are 2 hydrogens and 1 oxygen, this gves a mass of 18. The mass can be found on the periodic table.
What the molecular mass of MgF2?
The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.
What is the relative mass of so2?
The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.
What is the relationship between molecular mass and vapour density?
The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.
