By analyzing the combustion, it was found that a 1.3020g sample produced 2.7244g CO2, 0.5575g H2O, and 0.99151g SO2. From this, the empirical formula of thiophene can be determined by finding the percentage of each element and calculating their atomic ratio. ...
The problem:A compound of X and Y is 1/3 X by mass. The atomic mass of element X is 1/3 the atomic mass of element Y. Find the empirical formula of the compound. My work: Xa / (Xa + Yb) = 1/3 X = 1/3Y (1/3Y)a/((1/3Y)a + Yb) = 1/3 ...
The empirical formula for any compound can be determined in a few easy steps. The procedure involves finding the amount of each element in the compound and converting that amount to moles, followed by individual mole ratio calculations. Once the individual mole ratios are calculated, the ratios c...
