If the number of moles of gas decrease what happens to the volume?
According to Avogadro's Law, the number of moles is proportional to the volume. Therefore, if the number of moles of gas decreases, the volume also decreases.
What volume will 3.12 moles of SF6 gas occupy if the temperature and pressure of the gas are 141 degree celsius and 7.77 ATM?
The volume is 13,64 L.
What is the volume of 0.8 moles of chlorine gas at Standard Temperature and Pressure?
At STP, 1 mole of gas occupies a volume of 22.4 liters. Thus, 4/5 moles of gas will occupy .8*22.4 liters.
How are pressure volume and temperature of gases related?
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
What happens to temperature if pressure goes down and volume stays the same?
Yes. Since pressure and volume are inversely related, volume decreases when pressure increases (as long as temperature is constant). Consider the equation: PV=nRT, where n = moles, T is in degrees Kelvin, and R is the gas constant 0.082. Do the algebra and see how: P=nRT/V and the inverses become more easily understood.

What volume will 3.56 moles of methane occupy at STP?
This volume is 79,79 litres.
What is the volume of 0.8 moles of chlorine gas at Standard Temperature and Pressure?
At STP, 1 mole of gas occupies a volume of 22.4 liters. Thus, 4/5 moles of gas will occupy .8*22.4 liters.
What volume does 0.685 moles of gas occupy at stp?
The volume is approx. 15,35 litres.
What volume does 34.53 moles of a gas occupy?
Approx. 774 litres.
How many moles of oxygen are there in a thirty six centimeter cube of the gas at room temperature and pressure?
What you need to know to work this out is that:- Moles of gases at standard temperature pressure (With P and T constant) are proportional to the volume they occupy, divided by their specific gas constant.
How are pressure volume and temperature of gases related?
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
When the volume of a gas decreases was happens to its pressure?
The formula you need to remember is PV = nrT (and this is a closed system). P = pressure, V = Volume, n = moles of gas, r is a constant and T = temperature. So if the volume decreases, the pressure must increase in order for the equation to remain balanced. Plug some fake numbers in if that helps. Just remember that PV has to equal nrT
How many moles of gas occupy 1.3 L at a pressure of 3.89 atmospheres and a temperature of 323 K?
The answer is 0,19 moles.
What happens to temperature if pressure goes down and volume stays the same?
Yes. Since pressure and volume are inversely related, volume decreases when pressure increases (as long as temperature is constant). Consider the equation: PV=nRT, where n = moles, T is in degrees Kelvin, and R is the gas constant 0.082. Do the algebra and see how: P=nRT/V and the inverses become more easily understood.
What is the name of the scientific law air pressure and volume?
The scientific law that relates air pressure and volume is Boyle's law. It states that at a constant temperature, the pressure exerted by a gas is inversely proportional to its volume. In other words, as the volume of a gas decreases, its pressure increases, and vice versa.
