Answer:
the percent by mass of 14.29g of iron in a 32.44g sample of iron chloride is 44.05%
Step-by-step explanation:
the percentage by mass of substance can be calculated by dividing the mass of substance by the mass of the compound it contains, then, multiplied by 100.
percent by mass = mass of Fe/mass of FeCI2×100
according to this question, a 32.44g sample of iron chloride is found to contain 14.29 g of iron. the percent by mass of Fe is:
percent by mass = 14.29/32.44×100
percent by mass = 44.05%.
therefore, the percentage by mass of 14.29g of iron in a 32.44g sample of iron chloride is 44.05%.
