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 methyl acetate, chloroform, ethanolamine, diethylamine, and tetrahydrofuran. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safe Data Sheets (MSDS), the chemist finds the following information: liquid methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml -1 1.5 g ml 1.0 g ml 1 0.71 g ml 0.89 g ml. Next, the chemist measures the volume of the unknown liquid as 1005. cm' and the mass of the unknown liquid as 1.49 kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the data above, is it possible to identify the liquid? If it is possible to identify the liquid, do so. 0 yes no methyl acetate. chloroform ethanolamine diethylamine tetrahydrofuran 0.P

A mountain hiker found a chunk of shiny metal on the trail.  He wanted to find out the identity of the substance so he took the chunk of metal to the lab to determine the density.  The hiker placed the metal on a balance and determined the mass.  The hiker then took the metal and determined the volume by displacement. Determine the density and identity of the shiny metal.  Describe how the hiker could determine this, describe the equipment and the procedure.   be sure to show the work to calculate the value. mass  240.4  Ounces Initial Volume 65.3 Fluid Ounces Final Volume 87.9 Fluid Ounces Aluminum 2.70 g/mL Silver        10.5 g/mL Copper     8.96 g/mlL Gold         19.3 g/mL Titanium   4.54 g/mL  Platinum    21.4 g/mL

A mixture of methane (CH₄) and butane (C₄H₁₀) at one atmosphere pressure and 25°C has a density of 1.269 g/L. Assuming ideal behavior, what is the mass in grams of carbon that are in 1 liter of the mixture?   Someone please answer this instead of posting a link.
