Question

Quizplus · Accepted Answer

To find the mass of phosphorus that contains the same number of molecules as 4.23 g of sulfur, we first calculate the number of moles of sulfur in 4.23 g. The molar mass of S8 is 256.52 g/mol. Thus, moles of S8 = 4.23 g / 256.52 g/mol = 0.0165 mol. Since the number of molecules is the same, we need 0.0165 mol of P4. The molar mass of P4 is 123.88 g/mol. Therefore, the mass of P4 = 0.0165 mol * 123.88 g/mol = 2.04 g.
