Why are moles and volume directly proportional?
Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
What is the volume of 1.5 moles of gas at STP?
According to the mole concept: 1 mole of a gas occupies 22.4 Liters of a gas. So, 1.5 moles of gas occupies of gas. Hence, the volume of carbon dioxide occupied by it is 33.6 L.
What is the volume of 2 moles of oxygen gas at STP?
Answer. 1mol O2 occupies 22.4L of volume at STP. so 2mol O2 occupies 44.8L of volume at STP.
What is the volume of 1.75 moles of oxygen gas at STP?
The answer is 39.2L .
What is the volume of 1.5 moles of oxygen gas at room temperature and pressure?
What is the volume of 1.5 moles of oxygen gas at standard temperature and pressure (STP)? 22 L.
Which volume of oxygen is measured at room temperature and pressure for complete combustion?
Therefore, 550cm3 of oxygen is needed.
How do you find moles with pressure volume and temperature?
For example, if you want to calculate the volume of 40 moles of a gas under a pressure of 1013 hPa and at a temperature of 250 K, the result will be equal to: V = nRT/p = 40 * 8.3144598 * 250 / 101300 = 0.82 m³ .
What is the volume of 3 moles of oxygen gas at STP?
3×22
How do you find the volume of oxygen gas?
Calculate the volume (in cubic meters) of gaseous oxygen using the ideal gas law: multiply the amount of oxygen (in moles) by temperature and the molar gas constant followed by dividing the product by pressure.
What is molar volume of a gas What will be the volume of 3 moles of oxygen gas at STP?
We now know that the volume of 2.155 × 10-3 moles of oxygen is about 52.88 cm3. Use this information to calculate the volume of one mole of oxygen. (Your answer may not be exactly this figure, but should be close to it.) At STP, all gases have the same molar volume, which is about 24,000 cm3.
What is the volume of one mole of oxygen at STP?
22.4 L
What is the value for volume at STP?
22.4 L per mole
What is the volume of 1 kg of oxygen?
The volume of 1kg of oxygen gas at NPT is 0.7m3 . Specific heat of oxygen at constant volume is 653Jkg-1k-1 .
What is the volume of 2 moles of oxygen?
Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .
What is the volume occupied by 4.20 moles of oxygen gas?
0.08205L
What is the volume of 2 moles of nitrogen gas at STP?
Explanation: One mole of gas has a volume of 22.4L at STP. Since there are two moles of gas present, the volume is doubled.
What is the volume of oxygen required at STP to completely?
1.5 moles of oxygen at stp = 22.4 x 1.5 = 33.6 litres.
What is the volume of O2 required at STP for the oxidation of 1 l of SO2?
⇒ 22.4 L of O2 is required for the oxidation of 22.4 L of SO2. ⇒ 1 L of O2 is required for the oxidation of 1 L of SO2.
What is the volume of 4.5 moles of nitrogen gas at STP?
In chemistry, the volume or space that 1 mole of any gas occupies at STP is given as 22.4 liters, or 22.4 liters/1 mol. By using this information, the calculation to find the volume of 4.5 moles involves multiplying 4.5 mole by 22.4 liters/1 mol.
Which gas occupies the highest volume at STP?
Argon
What is true at STP?
STP stands for standard temperature and pressure and it is at a temperature of 0 degrees Celsius or at 273 Kelvin and at a pressure of 101.325 kPa or 1 atm. For gases, at this temperature it was established that for every one mol of a gas it is equivalent to 22.414 Liters.
What is the molar volume of a gas at STP?
What volume would 3.01 x10 23 molecules of oxygen gas occupy at STP?
11.2 liter
