So Percent purity is the ratio of the mass of the pure substance to the mass of the impure sample, expressed as a percentage. This is very similar to the percent yield, and to calculate percent purity, we use g pure X 100% g impure Let's try an example. 1.00g Fe ore contains 0.6g Fe metal. What is the percent purity? 0.6/1.0 X 100% = 60 %
The percent composition (percentage composition) of a compound is a relative measure of the mass (or weight) of each different element present in the compound. % by mass of oxygen + % by mass of hydrogen = 100 % (% by mass of water molecule).For any element present in any molecule:And, if you add together the % by mass of every element present in the compound the result will be 100%. a Y b Z c :Calculate the percent by mass (weight) of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl). Calculate the percent by mass (weight) of each element present in sodium sulfate (Na 2 SO 4). by mass of oxygen + % by mass of hydrogen = 100 % (% by mass of water molecule). For any element present in any molecule: And, if you add together the % by mass of every element present in the compound the result will be 100%. a Y b Z c :
