With the mass percent of Fe, oxalate ion, and water; find the mass percent of potassium ion in the complex iron salt difference.
Fe= 11.37%
H2O= 12.24%
oxalate= 28.01%
I don't understand the question.
mass percent by difference would be 100- (11.37+12.24+28.01)
To find the mass percent of potassium ion in the complex iron salt difference, we need to know the mass percent of the other components present in the complex salt. From the information provided, we have the mass percent of Fe (iron), oxalate ion, and water.
The mass percent of potassium ion can be calculated by subtracting the sum of the mass percentages of Fe, oxalate ion, and water from 100%. This is because the mass percentage of all components in a compound should add up to 100%.
Let's calculate the mass percent of potassium ion in the complex iron salt difference step by step:
Step 1: Determine the mass percentage of Fe, oxalate ion, and water.
Fe = 11.37%
H2O = 12.24%
Oxalate = 28.01%
Step 2: Add the mass percentages of Fe, oxalate ion, and water.
11.37% + 12.24% + 28.01% = 51.62%
Step 3: Subtract the sum obtained in Step 2 from 100%.
100% - 51.62% = 48.38%
Therefore, the mass percent of potassium ion in the complex iron salt difference is approximately 48.38%.
