1.00 mL of water at 25 C is heated to 100 C, at which point it boils at an atmospheric pressure of 1 atm and is vaporized. What is the difference in volume (in mL) when this happens? (At 25 C, liquid water has a density of 0.997 g/mL.)
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?

Liquid nitrogen has a density of 0.808 g/mL and boils at 77 K. Researchers often purchase liquid nitrogen in insulated 185 L tanks. The liquid vaporizes quickly to gaseous nitrogen (which has a density of 1.15 g/mL at room temperature and atmospheric pressure) when the liquid is removed from the tank. Suppose that all 185 L of liquid nitrogen in a tank accidentally vaporized in a lab that measured 10.00 m times 10.00 m times 3.50 m. Part A What...
Part 1. The air in a bicycle tire is bubbled through water and collected at 25∘C. If the total volume of gas collected is 5.60 L at a temperature of 25∘C and a pressure of 760 torr, how many moles of gas were in the bicycle tire? - Part 2. A 295-mL flask contains pure helium at a pressure of 755 torr . A second flask with a volume of 480 mL contains pure argon at a pressure of 714...
Please just answer Part 2

H0HOg) Assume that at exactly 100.0°C and 1.00 atm total pressure, 1.00 mole of liquid water and 1.00 mole of water vapor occupy 18.80 mL and 30.62 L, respectively 5th attempt d See Periodic Table See Hint (0.5 point) Part 1 Calculate the work done on or by the system when 1.85 mol of liquid H20 vaporizes. 5736.23319:J (0.5...
Gallium metal melts at 29.8°C. At the melting point the density of the solid is 5-90 g/ml, and that of the liquid is 6.10 g ml. a Does solid gallium expand or contract when it is melted? contracts Explain The same amount of mass occupies space in the liquid phase than in the solid phase. 6. What is the change in volume when 6.10 mL (cm) of solid gallium is melted? Volume by mi Reference Lt 30.0°C.Calculate the change in...
theres 2 parts to the question. only answer it if u
can answer both part 1 and 2
See page 295 A common anesthesia gas is Halothane, with the formula C2HCIBrF3 and the structure is shown in the figure. Liquid Halothane has a density of 1.87 g/mL, and boils at 50.2°C and 1.00 atm. Part 1 (1 point) See Periodic Table If Halothane behaved as an ideal gas, what volume would 10.0 mL of Halothane occupy at 60°C and 1.00...
