What is the volume of 10.9 mol of helium at STP?
The volume of 10.9 mol of helium at STP is 50 litres.
How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
What is meant by a volume of STP?
Most commonly, this refers to the volume of a gas at Standard conditions of Temperature and Pressure (often abbreviated, STP). This standard allows accurate comparisons of volumes. The volume of a gas (any gas) at STP is 22.4 liters per mole.
What volume will 3.56 moles of methane occupy at STP?
This volume is 79,79 litres.
What volume will the Cl2 occupy at STP?
stupid question
Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.
Why is nitrogen gas at STP less dense than Xe gas at STP?
atoms have a higher mass than molecules. Because both gases at STP have the same number of molecules per unit volume, the gas must be denser.
What is the calculated molar volume of the dry CO2?
22.4 liters at STP
How many liters are in 5.4x1024 molecules of nitric oxide at STP?
The volume is 19,48 L.
Which closed cylinder contains the same number of gas molecules at STP as a 4.0 liter closed cylinder containing O2 gas at STP?
ANY closed cylinder of 4.0 litre will contain the same number of molecules of ANY gas as the 4.0 liter closed cylinder containing O2 gas at the SAME temperature and pressure, since then the volume only depends on the number of molecules, not on the kind of molecules of the gasses concerned
How many molecules are in 100 L of potassium hydroxide solution at STP?
The number of molecules in a given volume of solution depends on the concentration of the solute. Because the concentration is not provided, this question has too little information to answer.
How many molecules are in 30 liters of methane (CH4) at STP?
How many molecules are in 30 liters of methane (CH4) at STP
What is the volume of 10.9 mol of helium at STP?
The volume of 10.9 mol of helium at STP is 50 litres.
What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
The chemical formula for h20 contains how many water molecules?
It contains 6.023 x 1023 molecules of water. the number is called Avogadro's Number and it is valid under STP conditions
How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
What is molar volume of hydrogen at stp?
