Given mass=53g Molar mass of Na2CO3 = 23×2+12+48 = 46+60= 106g No. Of moles = given mass /molar mass = 53/106 =0.5 Now 1 mole = 6.02×10^23 atoms So, 0.5 moles = 0.5×6.02×10^23. = 3.010×10^23 atoms

Tanushree Mukherjee 2 years, 4 months ago

Hydrogen — 4.07% Carbon–24.27% Chlorine—71.65% Molar Mass Is 98.96G To Calculate Empirical Formulae, first, we have to divide the given percentages of atoms by their molecular masses. Hydrogen — 4.07 / 1 = 4.07 Carbon–24.27 / 12 = 2.02 Chlorine—71.65 / 35.5 = 2.01 Now we have to divide all the values with the lowest obtained value. Hydrogen — 4.07 / 2.01 = 2 Carbon–2.02 / 2.01 = 1 Chlorine— 2.01 / 2.01 = 1 Therefore, the empirical formula is CH2Cl To Calculate Molecular Formulae, we need to find the weight of the empirical formula CH2Cl 12 + 2*1 + 35.5 = 49.5 The molecular weight- 98.96 is double of empirical weight. Therefore molecular formula is C2H4Cl2

Matter has been one of the most important subjects of research for the science enthusiasts. Scientists and philosophers have always tried to simplify things and so was the case with the matter. They wanted to know about the fundamental particles that make matter, their properties, structure etc. This led to the formulation of a number of atomic theories.
