since we know that the total pressure is 670 mmhg and the pressure of water at 20 c is 17.5 mmhg, we use dalton's law.
670=17.5+ gas pressure
652.5=gas pressure by definition
then we use the law P1V1T2=P2V2T1
tp find V2=47.9969 L

40 liters of gas were collected over water when the barometer read 622.0 mm Hg and temp was 20C what volume wuould dry gas occupy at standard conditions?
The gas would occupy 40 liters of space, by volume. This is only true as long as the conditions were normal.
A balloon is filled with helium. Its volume is 4.2L at 312.K. What will its volume in liters be at 285.K assuming no change in pressure?
Assuming pressure is constant, like you said, volume and temperature have a direct relationship. As temperature increases, volume increases; as temperature decreases, volume decreases. Setting up a algebraic direct proportion, you get approximately 3.84 liters for the balloon at 285 degrees K.
Assuming no change in temperature and pressure calculate the volume of O2 in liters required for the complete combustion of 14.9 L of butane C4H10?
Assuming no change in temperature and pressure, calculate the volume of O2 (in liters) required for the complete combustion of 14.9 L of butane (C4H10):
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 is the volume of one mole of any gas at STP?
At STP, 1 mol or 6.02x10^23 representative particles, of any gas occupies a volume of 22.4 Liters. (chemistry)

What is the volume occupied by 0.25 mol of chlorine gas?
The volume of one mole of gas at a standard temperature and pressure is 22.4 liters. Multiply 22.4 liters by 0.25 moles to get a volume of 5.6 liters.
If oxygen gas is collected over water at temperature of 10C and pressure of 1.02 ATM and the volume of gas plus water vapor collected is 293 mL then what volume of oxygen at STP was collected?
fly
When A balloon has a volume of 10500 liters and the temperature is 15 and degC. If the temperature were -25 and degC what would the volume of the balloon be?
It would be approx 9042 litres.
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?
3.5 litre if pressure is kept constant.
A balloon is filled with helium. Its volume is 4.2L at 312.K. What will its volume in liters be at 285.K assuming no change in pressure?
Assuming pressure is constant, like you said, volume and temperature have a direct relationship. As temperature increases, volume increases; as temperature decreases, volume decreases. Setting up a algebraic direct proportion, you get approximately 3.84 liters for the balloon at 285 degrees K.
Does gas possess definite volume at a definite temperature?
Of course. But at STP, any gas has a standard volume of 22.4 Liters.
If a beaker had 160 liters of water what is the volume?
Liters is a measurement of volume. 160 Liters is the volume.
What volume is occupied of 2.4 moles of chlorine?
54 liters at STP (standard temperature and pressure)
What volume is occupied of 0.48 moles of hydrogen?
0.48 liters at STP (standard temperature and pressure)
What determines the volume of gas?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
