Molecular weight of Ethane
››More information on molar mass and molecular weight In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the
Molar mass of H2C2O4*2H2O
Formula in Hill system is C2H6O6 Computing molar mass (molar weight) To calculate molar mass of a chemical compound enter its formula and click ‘Compute’. In chemical formula you may use: Any chemical element. Capitalize the first letter in chemical symbol
how do i calculate the relative atomic mass of …
· Ammonia is not an element so it doesn’t have an atomic mass. Maybe when you take your first chemistry course you’ll learn about that. Its molecular mass is the sum of the atomic masses of all the atoms in a molecule. (or actually in a mole of molecules)
The molecular weight (or molar mass) of a substance is the mass of one mole of the substance, and can be calculated by summarizing the molar masses of all the atoms in the molecule. Components in Dry Air Air is a mixture of several gases, where the two most
Properties of Hydrates It is generally possible to remove the water of hydration by heating the hydrate. The residue obtained after heating, called the anhydrous compound, will have a different structure and texture and may have a different color than the hydrate.
help with chemistry please?
· Relative Formula Mass(RFM) of ZnO= 81 81g= 1 mole of ZnO 27.1g= 27.1/81 = 0.335 moles of ZnO Relative Molecular Mass(RMM) of H2O= 18 18g= 1 mole of H2O 11.0g= 11.0/18 = 0.611 moles of H2O The required ratio of the no of moles of ZnO to that of H2O is
Empirical Formula of hydrocarbon by Combustion …
· Hydrocarbon + O2 >>> H20 + CO2 The goal is to find out how many moles of “carbon” are in the CO2 and how many moles of “hydrogen” are in the water. Once you know these numbers, then you should be able to get the empirical formula. Since the

The Relative Formula Mass can be written as M r or RFM. For example, the mass of one mole of carbon dioxide (CO 2) is (1 x RAM of carbon) + (2 x RAM of oxygen) = (1 x 12) + (2 x 16) = 44 g. So, one mole of carbon dioxide has a mass of 44 g. The of is 44. (),
