Part B: Density of a liquid.
unknown number #118
First add 10 ml of the unknown liquid......
Erlenmeyer Flask + stopper = 32.3540 g
Erlenmeyer Flask + stopper + unknown liquid (10.00ml) = 41.3460 g
Then add another 10.00 ml of unknown liquid into the flask, so that the sample is 20.00 ml
Erlenmeyer Flask + stopper + unknown liquid (10.00 ml + 10.00 ml = 20.00 ml) = 49.9595 g

18. An unknown liquid has a density of 1.32 g/mL. What is the volume of a 14.7-8 sample of the liquid? a. 11 ml b. 11.1 mL c. 11.13 mL d. 11.14 mL e. 11.136 ml
What is the effect on the calculated density of the unknown metal or liquid under the following conditions? After the flask was filled with unknown liquid the cover slip was placed on top. In doing so a small air bubble was trapped under the cover slip. When determining the density of the unknown metal, the flask was filled less than one quarter way with the metal instead of halfway. When determining the volume of the flask, the student did not...
Pre-Lab Questions Name 1. At 25 °C, 10 0181 g of an unknown liquid has a volume of6.75 mL a. Calculate the density b. Which of the following liquids was the unknown? water toluene chloroform Density, gmL at 25 ℃ 0.9982 0.8669 1.4832 If the unknown liquid had been water, what would the volume have been? c. d. What mass would a 10.00 mL sample of each of the other two liquids have been? Toluene Chloroform
A laboratory group measures an excess of an unknown liquid. They add this to an empty flask for which they calculate the volume. They heat the sample in a water bath until all liquid has been vaporized for several minutes. the sample is cooled and measured. Use their laboratory data (listed below) to answer the following questions: Calculate the mol of gas in the flask using the ideal gas law: Calculate the molar mass of the unknown: If a student...
Your task is to find the density of a liquid. You mistakenly fill the 10 mL volumetric flask all the way to the top, to overflowing, and find the mass of the overfull flask. Then you subtract the mass of the empty flask to get the mass of the liquid. In your calculations, you use 10 mL as your volume; will your result (the calculated density) be too high or too low? Explain.
Could someone assist me with this question? In the 19th century, J. B. A. Dumas devised a method for finding the molar mass of a volatile liquid from the volume, temperature, pressure, and mass of its vapor. (next column). He placed a sample of such a liquid in a flask that was closed with a stopper fitted with a narrow tube, immersed the flask in a hot water bath to vaporize the liquid, and then cooled the flask. Find the molar mass...
It was important that the flask be completely dry before the unknown liquid was added so that water present would not vaporize when the flask was heated. A typical single drop of liquid water has a volume of approximately 0.05 mL. Assuming the density of liquid water is 1.0 g/mL, how many moles of water is in one drop of liquid water, and what volume would this amount of water occupy when vaporized at 100°C and 1 atm?
