### Author Sal KhanHow to determine empirical formula from combustion analysis

Jul 12,2019 Calculate empirical formula when given percent composition#0183;(Molar mass of empirical formula) n = Molar mass of molecular formula.Since the empirical formula of our compound is C 3 H 4 O 3,it follows that its empirical formula molar mass is (3 x 12.00g/mol) + (4 x 1.00 g/mol) + (3 x 16.00 g/mol) = 36.00 g/mol + 4.00 g/mol + 48.00 g/mol = 88.00 g/mol.Next,we can write that (88.00 g/mol) n = 176.00 g/mol.Therefore,An inorganic salt given the following percentage For this we make table as:Element%CompositionAtomic MassMolar RatioSimple RatioNa29.11%23(29.11/23)(1.266/1.266)=1 Calculate empirical formula when given percent composition#215; 2=2S40.51%32(40.51/32)(1.266/1.266)=1 Calculate empirical formula when given percent composition#215; 2=2O30.38%16(30.38/16)(1.898/1.266)=1.5 Calculate empirical formula when given percent composition#215; 2=3 Formula is N a2 S 2 O3 .6.7 Mass Percent Composition from a Chemical Formula Jan 15,2019 Calculate empirical formula when given percent composition#0183;The subscripts in the formula are first used to calculate the mass of each element in one mole of the compound.That is divided by the molar mass of the compound and multiplied by 100 %.(6.7.1) % by mass = mass of element in 1 mol molar mass of compound Calculate empirical formula when given percent composition#215; 100 %
