A company that manufactures baseball bats believes that its new bat will allow players to hit the ball 30 feet farther than its current model. The owner hires a professional baseball player known for hitting home runs to hit ten balls with each bat and he measures the 90% confidence interval for the true difference between the mean distance hit with the new model and the mean distance hit with the old model. Round the endpoints of the interval to one decimal place, if necessary.

8 AM Wed Nov 6 www-awy.aleks.com Measurement and Matter Calculating mass density A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of acetone, methyl acetate, ethanolamine, diethylamine, and dimethyl sulfoxide. The chemist plans to try to identify the unknown liquid by measuring its density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density --- --- acetone 0.79 g/cm^3 methyl acetate 0.93 g/cm^3 ethanolamine 1.0 g/cm^3 diethylamine 0.71 g/cm^3 dimethyl sulfoxide 1.1 g/cm^3 Next, the chemist measures the volume of the unknown liquid as 0.685 L, and the mass of the unknown liquid as 483. g. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the density, is it possible to identify the liquid? O yes O no If it is possible to identify the liquid, do so. acetone methyl acetate ethanolamine diethylamine dimethyl sulfoxide
