Answer:
36.09% is the mass percent composition of calcium in calcium chloride
Explanation:
Mass percent is defined as one hundred times the ratio between the mass of a compound (In this case, Calcium), and the total mass of the sample:
Mass Percent = Mass compound / Total mass of the sample × 100
Computing the values of the problem:
Mass Percent = 0.690g / 1.912g * 100
Mass percent =
36.09% is the mass percent composition of calcium in calcium chloride
