what is the total mass in grams of oxygen in a room measuring 4.0 m by 5.0 m by 2.5 m? assume that the gas is at STP and that air contains 20.95% oxygen by volume
Section 3.4 gas laws question
Imagine we have a balloon filled with argon gas and the room conditions are 1.00 atm and 25°C. Above what temperature would we have to heat the balloon so that it would float? Assume the partial...
A sample of gas under a pressure of 22.0 kPa has a volume of 33.0 cm3. The pressure is increased to 888 kPa, while the temperature remains constant. What volume will the gas occupy at this pressure...
The pressure exerted by a gas is 38.0 atm while it has a volume of 350 cm3. What would be the volume of this sample of gas at standard atmospheric pressure? must show units, and must...
The pressure exerted by a gas is 45.0 atm while it has a volume of 475350 cm3. What would be the volume of this sample of gas at standard atmospheric pressure? must show units, and...
answers must show units, and must be rounded to the correct number of significant digits. Pressure for STP in atmospheric units (atm) is 1.0, STP for kilopascals (kPa) is 101.3 kPa The pressure...
need help figuring out what equation to use, and need a good explanation of why and how it works in laymens terms. got lost in chemistry class sometime last week, and need help cataching back up!...
Gas (A) Methane, (B) Ethane, (C) Propane, (D) Butane
D. HBr and NH3
When using the gas laws and you are given 3 out of the 4 items, how do you know which order to place them in to find the answer for each law? & Is this the same for each law?
A gas sample at 356 K occupies a volume of 1400 m. At what temperature will it a occupy 1200 m?
