A student in chm 11500 lab measured the mass of a 250-ml erlenmeyer flask and recorded it as 79. 83 g. She added 10. 00 ml of deionized water from a 25-ml buret to the flask. The mass of the flask plus the water was 89. 82 g. The temperature of the water was 22 °c. What is the calculated volume of the water that the student measured?.

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
