An analytical chemist measures the amount of Elements E₁ and E₂ in four samples of an unknown Substance X: mass of sample mass of E2 1 2 3 4 6.2 g 24.8 g Using this information, answer the questions in the table below. 3.6 g 14.4 g 7.0 g 18.0 g 6.0 g 24.0 g It's known that X contains no elements other than E₁ and E₂. 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. pure substance O mixture (can't decide) g x10 X
