What is the chemical formulae for potassium oxide?
We know that K2O is the chemical formula for potassium oxide.
What is the mass of K2O contain equal number of moles of K atoms as are present in 1kg of KCl?
This mass is 631,75 g K2O.
What are some advantages of molecular formulae?
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
The molecular mass of Vitamin C?
The molecular mass of vitamin C (ascorbic acid) is 176,1241 and the chemical formula is C6H8O6.
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.

What Ionic compound of K2O?
The ionic compound of K2O is potassium oxide. It is formed from the combination of potassium (K) cations and oxide (O) anions. Its chemical formula is K2O.
What is the chemical formula of ionic compound potassium oxide?
Three potassium oxides are known: K2O, KO2, K2O2.
What mass of potasium oxide is formed when 7.8g of potasium is burned in oxygen?
When potassium is burned in oxygen, it forms potassium oxide according to the balanced chemical equation: 4K + O2 → 2K2O. The molar mass of K is 39.10 g/mol and that of K2O is 94.20 g/mol. Using stoichiometry, we find that 7.8g of potassium will form 7.8g * (1 mol K / 39.10 g K) * (1 mol K2O / 4 mol K) * (94.20 g K2O / 1 mol K2O) = 4.57g K2O.
What is the sum of atomic mass?
I suppose that you think to atomic weights (not mass) of chemical elements and the molecular mass.
What are some advantages of molecular formulae?
