Question
1) in an experiment, a student was asked to measure the density of an unknown liquid. He was given a small flask, which he found to have a mass of 32.6195 grams when empty. He filled the flask with water at 21.6 C and found the full flask to have a mass of 156.8995 grams. The student then emptied and dried the flask and then filled the flask with an unkwown liquid. The mass of the flask filled with unknown liquid was 134.2515 grams.
A) determine the volume of the flask
B) determine the density of the unknown liquid. SHOW WORK
2) using the same flask as in question #1, the student emptied and dried the flask, added some chunks of an unknown solid to the flask, and found that the mass of the flask with the solid was 330.2117 grams. Leaving the solid in the flask, the student added some water at 22.3C until the flask was completely filled. The mass of the flask with solid and water was 418.1522 grams. determine the density of the unknown solid. Show work
Explanation / Answer
1 : Mass of water in flask = 156.8995 - 32.6195 = 124.28g
Water at 21.6
