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 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 Safety Data Sheets (MSDS), the chemist finds the following information: liquid methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml 1.5 g ml 1 -1 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 gml. yes no methyl acetate chloroform ethanolamine…

Some people like to make their own hand lotion because it can be less expensive than buying it and they have the ability to add only the fragrances that they like. A recipe for hand lotion calls for mixing 253 g of water (H₂O) with 264 g of glycerin (C3H8O3). This recipe makes a total of 685 mL of hand lotion. Incorrect. What is the mass percent of glycerin in the hand lotion? i ! % Hint The mass percent is the concentration of the solution as the percent of solute in a given mass of solution. Assistance Used

Before investigating the scene, the technician must dilute the luminol solution to a concentration of 5.00 x 10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray? Express your answer with the appropriate units.
