At constant pressure, density of gas is inversely proportional to its temperature. This is how hot air balloon is floating in air: burning fuel makes inside air temperature higher and density lower; low density air balloon float on high density regular air. What is the density of air in g/L at 68 degree C if the atmospheric pressure is 1.0 atm? The average molar mass of air is about 29 g/mol. Keep two decimal places for your answer.

Question 21 pts

In Vinegar Analysis lab, at the end point of a titration, there is still a drop of NaOH solution hanging on the tip of burrette. How does this affect the experimental result in this lab?

Since this drop did not have a chance to react with acetic acid, it should not affect the experimental result.

Since this drop of NaOH did not have a chance to react with acetic acid in vinegar, it will make the experimental result lower.

Since this drop will make the volume of NaOH artificially higher, it will make the experimental result higher as well.

At constant pressure, density of gas is inversely proportional to its temperature. This is how hot air balloon is floating in air: burning fuel makes inside air temperature higher and density lower; low density air balloon float on high density regular air. What is the density of air in g/L at 76 degree C if the atmospheric pressure is 1.0 atm? The average molar mass of air is about 29 g/mol. Keep two decimal places for your answer.

When fully inflated, a hot-air balloon has a volume of 1.6Ã105L at an average temperature of 383 K and 0.981 atm .

Assuming that air has an average molar mass of 29 g/mol, what is the density of the air in the hot-air balloon?
