What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
What is the relative molecular mass of caco3?
100 grams
How do you calculate the mass in grams of 6.073 molecoles of water?
You divide the 6.073 by 6.022x1023 (avagadros number) to get the moles, then multiply by molecular mass (18) to get mass in grams

How do you calculate Mr?
To calculate the relative molecular mass (Mr) of a molecule, add up the atomic masses of all the atoms in the molecule as shown in its molecular formula. For example, the Mr of H2O (water) is calculated by adding the atomic masses of 2 hydrogen atoms and 1 oxygen atom.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528

What formula is used to calculate the atomicity of elements?
atomic mass/molecular mass
Does 7Be and 7 Li have the same atomic mass?
As they are isobars, they have the same relative molecular mass.
How many moles of aluminum are present in 856g of aluminum sample?
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
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 the symbol Mr used for in chemistry?
Mr is the symbol for the relative molecular mass.
What is the relative molecular mass of phosphoric acid?
The rmm of phosphoric acid is 97.976898.
