Answer :
There is 37.6g of M in M₂O₃
Calculation
M₂O₃ = 55.4g
mass of O = 1.11 mole * 16g/mol = 17.76g
mass of M = 37.6g
What is gram and weight?
In the metric system, one thousandth (1 x 10-3) of a kilogramme is equal to one gramme. The mass of one cubic centimetre of pure water at 4°C was the original definition of the gramme (the temperature at which water has maximum density)
The molecular weight of a substance or the total mass of the atoms in its molecular formula is equivalent to one gramme of molecular mass. It equates to a molecule's molecular mass expressed in grammes.
The periodic table element's atomic mass is expressed in grammes. The mass of one mole in grammes for an element is known as its molar mass. One mole of an element has a mass equal to its gramme atomic mass. By converting the atomic weight of an element from the periodic table to grammes, it can be calculated.
