How many hydrogen molecules are in 31.8 L H2(g) at STP?
To find the number of hydrogen molecules, first calculate the number of moles in 31.8 L of H2 at STP using the ideal gas law. Then use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many moles of argon are found in a 5L sample of argon at STP?
At STP, 1 mole of any gas occupies 22.4 L. Therefore, in a 5L sample of argon at STP, there would be 5/22.4 moles of argon, which is approximately 0.223 moles.
How many liters are in 5.4x1024 molecules of nitric oxide at STP?
Using the ideal gas law (PV = nRT), we can calculate the volume of gas at STP. First, we need to convert the number of molecules to moles by dividing by Avogadro's number. Then, we can use the volume of 1 mole of gas at STP, which is 22.4 liters. Calculate V = (5.4x10^24 / 6.022x10^23) * 22.4 to find the volume in liters.
How many molecules are in 30 liters of methane (CH4) at STP?
At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. So, in 30 liters of methane, there would be 30/22.4 = 1.3393 moles. One mole of methane contains 6.022 x 10^23 molecules, therefore 30 liters of methane at STP would contain 1.3393 * 6.022 x 10^23 = 8.07 x 10^23 molecules.
How many molecules of SO2 gas would occupy 4.15 L at STP?
1.12 X10 to the 23rd power molecules SO2
How many hydrogen molecules are in 31.8 L H2(g) at STP?
To find the number of hydrogen molecules, first calculate the number of moles in 31.8 L of H2 at STP using the ideal gas law. Then use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.

How many moles are contained in 16.8 L of Xe gas at STP?
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
How many moles are present in 8.4 liters of nitrous oxide at STP?
8,4 liters of nitrous oxide at STP contain 2,65 moles.
How many oxygen molecules are in 9.1 L of oxygen gas at STP?
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
How many molecules are contained in 16.81 of Xe at STP?
To find the number of molecules in 16.81 grams of xenon (Xe) at standard temperature and pressure (STP), first calculate the number of moles using the molar mass of xenon, which is approximately 131.3 g/mol. The number of moles is 16.81 g / 131.3 g/mol ≈ 0.128 moles. Using Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol), the total number of molecules is 0.128 moles × (6.022 \times 10^{23}) molecules/mol ≈ (7.71 \times 10^{22}) molecules.
How many molecules of ethane are present in 64.28 liters of ethane gas (C2H6) at STP?
at STP 1 mole occupies 22.4 litres. 64.28 / 22.4 is 2.8696428 moles. Multiply this by avagadro's constant (6.022*10^23) gives 1.7281x10^24 molecules
How many moles of argon are found in a 5L sample of argon at STP?
At STP, 1 mole of any gas occupies 22.4 L. Therefore, in a 5L sample of argon at STP, there would be 5/22.4 moles of argon, which is approximately 0.223 moles.
How many moles of H2 gas are present in 6.0 L flask at stp?
The answer is 0,2675 moles.
How many moles of nitrogen does it take to fill a 60.0 liter space of stp?
The answer is 2,68 moles.
How many molecules are in a 1500 L room at STP?
At standard temperature and pressure (STP), 1 mole of gas occupies 22.4 L. Therefore, a 1500 L room would contain 1500/22.4 moles of gas. One mole contains 6.022 x 10^23 molecules, so you would multiply the number of moles by Avogadro's number to find the total number of molecules in the room.
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
