Question

Quizplus · Accepted Answer

The sample contains 10 moles of ^-³. The prefix "S" indicates the number of atoms of sulfur in each molecule, which is 1 in this case. The prefix "U" indicates the number of atoms of uranium in each molecule, which is also 1. The prefix "P" indicates the number of atoms of phosphorus in each molecule, which is 1 in the first molecule and 13 in the second molecule. Therefore, the total number of molecules in the sample is (10 x Avogadro's number) = 6.02 x 10^20.
