Consider a mixture of three different gases: 1.90 g of argon (molecular mass = 39.948 g/mol), 3.10 g of neon (molecular mass = 20.180 g/mol), and 4.00 g of helium (molecular mass = 4.0026 g/mol). For this mixture, determine the percentage of the total number of atoms that corresponds to each of the components.
