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.
I’m confused on where to start. Take me step by step.
An analytical chemist measures the amount of Elements E₁ and E₂ in four samples of an unknown Substance.

16.0 g 9.1 g
17.1 g 9.8 g
18.5 g 10.6 g
12.0 g 6.9 g
It's known that X contains no elements other than E₁ and E₂.
Using this information, answer the questions in the table below.
Is X a pure substance or a mixture?
If you don't have enough information to decide, choose can't decide.
If you said X is a pure substance, calculate the mass of Element E₁ the
analytical chemist would find in a new 10.0 g sample of X.
Round your answer to 2 significant digits.
O pure substance
O mixture
