What is the relative molecular mass of caco3?
The relative molecular mass of CaCO3 (calcium carbonate) is approximately 100.09 g/mol.
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.

The relative molecular mass of water?
Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.
What is the relative molecular mass of methane?
Methane has four hydrogen atoms attached to a central carbon atom. Their atomic masses are 1 and 12 respectively. The RMM of methane is 4x1+12=16.

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.
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 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.
The relative molecular mass of water?
Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.
What is the relative molecular mass of methane?
Methane has four hydrogen atoms attached to a central carbon atom. Their atomic masses are 1 and 12 respectively. The RMM of methane is 4x1+12=16.
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 molecular formula of relative mass of 72?
There are many compounds with a relative mass of 72.Eg. pentane (C5H12), methyl butane (CH3)-(C4H9), dimethyl propane (CH3)2-(C3H6). Inorganic formula's can not easily be guessed, but undoubtly be found.Only one (isotope of an) element has the relative mass of 72: Gallium, (Ga-72), but this is not a natural, stable isotope. Gallium has not a molecular formula (being a metal like aluminum) only an atomic symbol: Ga.
