An analytical chemist measures the amount of Elements E₁ and E₂ in four samples of an unknown Substance X: sample of E₁ mass mass of E₂ 1 3.7 g 30.3 g 4.6 g 15.4 g 3.2 g 25.8 g 3.4 g 27.6 g 2 3 4 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. Opure substance Omixture O (can't decide) 0 x10 X
