To find the percent by mass of calcium in the compound, first find the total mass of the compound by adding the mass of calcium (2.89g) to the mass of chlorine (5.11g), which equals 8.00g. Then, divide the mass of calcium by the total mass of the compound and multiply by 100 to get the percentage: (2.89g / 8.00g) * 100 = 36.1%.
