9.3% of the mass of sodium chloride is due to sodium. The other 60.7% of the mass is from chlorine. So, in a 100 g sample of sodium chloride, there are 39.3 g of sodium and 60.7 g of chlorine. This type of data is known as percent composition. The percent composition tells you the percentage by mass of an element in a compound. There is a convenient formula for finding the percent composition of an element in a compound: (obtained from periodic table) percent composition of element " X" mass.

Empirical formula =C3H7. Was this answer helpful?

STEP 1: Calculate the molar mass of the empirical formula. STEP 2: Divide the given molecular molar mass by the molar mass calculated for the empirical formula. STEP 3: Multiply each subscript by the whole number that resulted from step 2. This is now the molecular formula.

used as LPG and lighter fluid, contains 82.66% carbon and 17.34% hydrogen by mass. Complete the exercise belowusing 100.0 g sample to deduce the empirical (The empirical formula for a substance gives the relative numbers of its atoms (for C3H6 the empirical formula is CH2).

⇒Thus, empirical formula is CH2O. Q.

Divide both moles by the smallest of the results. Multiply each of the moles by the smallest whole number that will convert each into a whole number. Since the moles of O is still not a whole number, both moles can be multiplied by 2, while rounding to a whole number. Write the empirical formula.

Empirical formula CH3N.

11. Find the empirical formula for a compound that contains 82.4% nitrogen and 17.6% hydrogen. 5.89 is smaller than 17.4 For nitrogen: For hydrogen: Divide by the smallest: 5.89/5.89 = 1 17.4/5.89 = 2.95 →3.0 The formula therefore is N1H3, or just NH3.
