Volume of a gas at STP is 4.5 liters. To find volume at 40 psi and 80 degrees C, we use the ideal gas law: PV = nRT. At constant volume, we can ignore volume and rearrange to P1/T1 = P2/T2. Plugging in the values, we find the volume at 40 psi and 80 degrees C to be 1.25 liters. Hence, the right answer is B. 1.25.

How many moles of N2 are there at a temperature of 20 degrees Celsius 1 ATM pressure if the gas occupies 44 Liters?
The answer is 1,83 moles.
The volume of the balloon is 3 liters at a temperature of 300 degrees kelvin What will the volume of the balloon be if the temperature rises to 350?
Assuming pressure remains constant, we can use Charles's Law which states that the volume of a gas is directly proportional to its temperature. V1/T1 = V2/T2. Substituting the given values, we find that the new volume of the balloon at 350 K will be 3.5 liters.
What is the volume of 4000 liters of diesel?
The volume of 4000 liters of diesel is simply 4000 liters. It is a measurement of how much space the diesel occupies.
Which term describes how much space a substances occupies?
volume
Under what sets of condition will a 0.50 mole sample of helium occupy a volume of 11.2 liters?
A 0.50 mole sample of helium will occupy a volume of 11.2 liters under standard temperature and pressure (STP) conditions, which are 0 degrees Celsius (273.15 K) and 1 atmosphere pressure. At STP, one mole of any gas occupies a volume of 22.4 liters.
How many moles of N2 are there at a temperature of 20 degrees Celsius 1 ATM pressure if the gas occupies 44 Liters?
The answer is 1,83 moles.
What volume does 0.50 mole of NH3 at STP occupy?
0.50 moles of NH3 at STP (Standard Temperature and Pressure) occupies 11.2 liters of volume.
How can you calculate the number of liters of 2.30 mole of helium gas at STP?
1 mole (or 4 g of He) occupies 22.414 liters. So, 2.3 mole occupies 2.3 x 22.414 liters = 51.5522 liters
If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters the pressure of the gas in the cylinder will change from 70 kilopascals to what?
Assuming the temperature remains constant, we can use Boyle's Law which states that pressure and volume are inversely proportional at constant temperature. If the volume is halved from 8.0 liters to 4.0 liters, the pressure will double from 70 kilopascals to 140 kilopascals.
The volume of the balloon is 3 liters at a temperature of 300 degrees kelvin What will the volume of the balloon be if the temperature rises to 350?
Assuming pressure remains constant, we can use Charles's Law which states that the volume of a gas is directly proportional to its temperature. V1/T1 = V2/T2. Substituting the given values, we find that the new volume of the balloon at 350 K will be 3.5 liters.
One mole of oxygen gas at stp occupies 22.4 what?
One mole of any gas at STP occupies 22.4 liters. Therefore, one mole of oxygen gas at STP also occupies 22.4 liters.
How many liters are in 1.84 moles of helium?
1 mole occupies 22.414 liters So, 1.84 moles will occupy 41.242 liters
What if the volume of a cylinder is reduced from 8.0 liters to 4.0 liters what should be the pressure of the gas in the cylinder?
If the volume of a gas is reduced from 8.0 liters to 4.0 liters, and the temperature remains constant, the pressure will double according to Boyle's Law. Therefore, the pressure of the gas in the cylinder should increase by a factor of 2.
How do you calculate the number of liters of 3.30 moles of helium at stp?
1 mole occupies 22.414 liters So, 3.30 moles will occupy 73.966 liters.
