*THE EXPLANATION*
Lacy obtained a dry empty flask with a stopper and placed it on an analytical balance. She found the mass to be 36.765 g. Lacy then completely filled the flask with distilled water and forced all the air out with the stopper. she again weighed the stopper, flask, and water and obtained a mass of 65.264 g. she determined the volume of the flask she emptied and dried her flask and obtained the unknown liquid she completely filled the flask with her unknown liquid placed the stopper on as before and obtained a mass of 59.323 g
1) mass of the empty flask plus stopper
2) mass of stoppered flask plus water
3) mass of stoppered flask plus unknown liquid
4) mass of water
5)temperature in the lab
6) volume of flas (density of h20 at 25 degrees c 0.09970 g/cm^3 at 20 degrees c 0.9982 g/cm^3)
7) mass of liquid
8) density of liquid
