Molecular mass is the sum of atomic masses of all the atoms present in the molecule. We know that atomic mass of carbon is 12 u and that of oxygen is 16 u. Thus, molecular mass of carbon dioxide (C O 2) = (atomic mass of C) + 2 × (atomic mass of O) = (12 + 32) = 44 u.
Calculate the molecular mass of the following: CO2. View Solution. Q3
The molecular mass of chlorine. Chlorine exists as a diatomic molecule that is Cl 2.Atomic mass of Chlorine = 35.5 .Atomic mass of Hydrogen = 1 . Molecular Mass of Cl 2 = (Atomic mass of chlorine) x 2 = 35. 5 × 2 = 71 g / mol. Hence . Molecular mass of NH 3 = 17g/mol . Molecular mass of CO 2 = 44 g/mol. Molar mass of HCl = 36.5 g/mol ...
(Relative molecular mass of calcium carbonate is 100). (iii) What is the volume of carbon dioxide liberated at stp? (iv) What mass of calcium chloride is formed? (Relative molecular mass of calcium chloride is 111) (v) How many moles of HCl are used in this reaction?
0.2 mole of an alkane on complete combustion gave 26.4g of carbon dioxide. Find the molecular weight of alkane
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calculated whose chemical formula is given.
Atom may be regarded as comprising of protons, neutrons and electrons. If the mass attributed to a. neutron were halved and that attributed to the electron were doubled, the atomic mass of 6 C 12 would be
Sodium carbonate (Na2CO3) also known as washing soda or soda ash is a sodium salt of carbonic acid. It is generally prepared by ammonia soda or Solvey process. A common source of sodium carbonate is the ashes of plants sometimes called soda ash.
