A chemist measures the mass of an empty bottle to be 24.9233 g. She then transfers 22.1 mL of a liquid to the bottle and finds the total mass to be 64.8034 g. Given that density = mass/volume, determine the density of the liquid.

8 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 carbon tetrachloride, ethanolamine, tetrahydrofuran, pentane, and diethylamine. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density carbon tetrachloride 1.6...

A chemist had a bottle of HCl (aq) of unknown concentration. She performed a titration experiment in order to determine its concentration. She pipeted 25.00 mL of the HCl solution into an Erlenmeyer flask. She then added about 21 mL of deionized water and 3 drops of phenolphthalein indicator dye to the flask. She titrated this mixture with 0.09063 M NaOH (aq), and obtained a permanent, pale pink endpoint after the addition of 36.68 mL of NaOH (aq). Given that...

A bottle weighed 7.6500 g empty and 9.9700 g after introduction of an organic liquid with a density of 0.92 g/mL. The balance was equipped with stainless steel weights (d_w = 8.0 g/ml). Correct the mass of the sample for the effects of buoyancy. Report the mass to the same number of significant figures as the uncorrected mass.

In lab, an empty weigh boat measures 11.7 g. A piece of metal is added to the weigh boat, and the total mass increases to 19.5 g. A graduated cylinder is filled with 24.2 mL of water. The piece of metal is carefully added to the graduated cylinder, and the volume increases to 28.0 mL. Using this data, find the density of the piece of metal, in units of g/ml. Do not include units in your answer.
