You can use mass percent composition as a conversion factor between grams of a constituent element and grams of the compound. The conversion factor in each mass percent composition are (a) 11.19 g H‚ 100 g H₂O (b) 53.29 g O‚100 g fructose (c) 84.12 g C‚100 g octane (d) 52.14 g C‚100 g ethanol
The percent by mass of each element present in a compound is called Mass Percent.
(a) Water is 11.19% hydrogen by mass.
Here it is given mass of hydrogen is 11.19 %. That means 11.19 % of solute should be added in 100 g H₂O.
(b) Fructose, also known as fruit sugar, is 53.29% oxygen by mass.
Here it is given mass of oxygen is 53.29 %. That means in 53.29% of solute should be added in 100 g fructose.
(c) Octane, a component of gasoline, is 84.12% carbon by mass.
Here it is given mass of carbon is 84.12 %. That means in 84.29% of solute should be added in 100 g Octane.
(d) Ethanol, the alcohol in alcoholic beverages, is 52.14% carbon by mass.
Here it is given mass of carbon is 52.14 %. That means in 52.14% of solute should be added in 100 g Ethanol.
Thus from the above conclusion we can say that You can use mass percent composition as a conversion factor between grams of a constituent element and grams of the compound. The conversion factor in each mass percent composition are (a) 11.19 g H‚100 g H2O (b) 53.29 g O‚100 g fructose (c) 84.12 g C‚100 g octane (d) 52.14 g C‚100 g ethanol
