AI Generated Solution

To calculate the number of molecules in 124 g of phosphorus (P4), we can follow these steps: ### Step 1: Determine the Molar Mass of Phosphorus Phosphorus exists in the form of P4. To find the molar mass of P4, we need to multiply the atomic mass of phosphorus by 4. - Atomic mass of phosphorus (P) = 31 u - Molar mass of P4 = 4 × Atomic mass of P = 4 × 31 u = 124 g/mol ...
