QUESTION:
A 1.912-g sample of calcium chloride is decomposed into its constituent elements and found to contain 0.690 g Ca and 1.222 g Cl. Calculate the mass percent composition of Ca and Cl in calcium chloride.
ANSWER:Solution 73P
Here, we are going to calculate the percent composition of Ca and Cl in calcium chloride.
Step 1:
Mass percentage gives the concentration of an element in a compound. Mathematically, it can be calculated by the following formula:
Mass percent of an element X = (mass of the element X / total mass of compound) x 100 %
