You are asked to calibrate a 25 mL volumetric pipet. You determine that the temperature of your distilled water is exactly 24.5 degrees Celsius. You carefully determined the mass of a clean dry beaker and found that it was 57.5513 g. You pulled water up to the mark and transferred this to the beaker and found that the new mass was 82.9344 g. What is the actual volume of the pipet? The density of water at 24.5 degrees Celsius is 0.997983 g/mL.
how much space would a 0.434g sample of a material occupy if it has a density of 1.23gcm-3

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 ethanolamine, pentane, chloroform, acetone, and glycerol. 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: Next, the chemist measures the volume of the unknown liquid as 1049. cm and the mass of the unknown liquid as 1.07 kg.
Do temperature conversions in steps to obtain results with correct numbers of sig figures: 1) T = 670 K --> t°C = _____ 2) t°C = +3400 °C --> T = _____ 3) t°F = +120 °F --> t°C= _____
A hot water bath was made by adding about 250-mL of distilled water to a 400-mL beaker. The beaker was placed on a hot plate and heated until the water was about 70oC. 9.982 g KNO3 was added to a 25-mL graduated cylinder. About 8 mL of distilled water was added to the graduated cylinder and it was placed in the hot water bath. The mixture was stirred continuously with a temperature probe and heated until all the KNO3 dissolved. The solution was clear and colorless and the volume of this solution was 12.5 mL. (This initial solution is called Solution 1.) The graduated cylinder was removed from the hot water bath and, while continuing to stir, Solution 1 was allowed to cool. White crystals of KNO3 were first observed at 64.1oC. Solution 1 Mass of KNO3 9.982 g Volume of Solution 12.5 mL Crystallization temperature 64.1 C Calculate the Ksp value for KNO3 at the crystallization temperature.
