Computing formula mass work sheet. Find the formula mass of ca c⁴H⁴o⁴
Answer (1)
To calculate the formula mass (molar mass) of calcium acetate, Ca(C₂H₃O₂)₂, follow these steps:1. Identify the elements and their quantities:Calcium (Ca): 1 atomCarbon (C): 4 atomsHydrogen (H): 6 atomsOxygen (O): 4 atoms2. Use atomic masses:Calcium (Ca): approximately 40.08 uCarbon (C): approximately 12.01 uHydrogen (H): approximately 1.008 uOxygen (O): approximately 15.999 u3. Calculate the total mass:Calcium: 1 × 40.08 u = 40.08 uCarbon: 4 × 12.01 u = 48.04 uHydrogen: 6 × 1.008 u = 6.048 uOxygen: 4 × 15.999 u = 63.996 u4. Sum the masses:Total mass = 40.08 u + 48.04 u + 6.048 u + 63.996 u = 158.168 uTherefore, the formula mass of calcium acetate is approximately 158.168 unified atomic mass units (u).For a detailed walkthrough on calculating the molar mass of calcium acetate, you can refer to the following video:
