According to this, one mole of hydrogen gas at STP will occupy 22.4 L of volume. Therefore, 2 moles of hydrogen gas will occupy a volume twice of 22.4 L i.e. 44.8 L.
What is the volume of 2 moles of gas at STP?
Explanation: 1 mole of gas would take up 22.4 liters of volume, which is equivalent to 22.4 dm3 of volume. Therefore, multiply answer by 2 (since there are 2 moles), and hence you would get an answer of 44.8dm3 .
What is the volume of hydrogen in STP?
We know that at STP one mole of any gas occupies 22.4litres . It means that one mole of hydrogen also occupies 22.4litres of volume at STP. So 10moles of hydrogen gas will occupy =22.4×10=224litres of volume at STP.
What is the volume of 2.0 moles of oxygen gas at STP?
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 mass of 2 moles of hydrogen?
So two moles is 64 g. A mole is useful because it’s the number of atoms needed to convert atomic mass units into grams. So a mole of carbon is 12 grams. A mole of helium is 4 grams.
What gas occupies 22.4 at STP?
Oxygen gas is made up of diatomic molecules (O2). Therefore 22.4 L of oxygen gas at STP contains 1 mole of O2 molecules.
What is the volume of 0.5 moles of gas at STP?
0.5 moles⋅22.4 L/mol=11.2 L , and so on.
What volume does 1 mole of hydrogen occupy at STP?
One mole of any gas at STP will occupy 22.4 liters of volume.
What is the volume of 2.5 moles of H2?
The volume is 28.8 L .
What is the volume of 3 moles of hydrogen gas at STP?
Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L . Due to the new conditions of STP , the new molar volume using the ideal gas equation (PV=nRT) comes out as 22.7 L . 3mol ⋅22.7 Lmol =68.1 L .
What is the mass of 2 mole of oxygen gas at STP?
Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
What is the volume of 3.5 moles of O 2 gas?
The answer is 39.2L . The gas laws tell us that all ideal gasses behave identically under the same conditions. At STP, the molar volume of any ideal gas is equal to Vmolar=22.4L , which means that 1 mole of any gas at STP will occupy exactly 22.4L .
What is the volume of 0.50 moles of oxygen gas O2 at STP?
Is the molar mass of hydrogen 1 or 2?
However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.
How many moles of oxygen react with 2 moles of hydrogen?
From the above reaction, 2 moles of hydrogen will react with 1 mole of oxygen. Hence, 1 mole of oxygen is required.
Is H2 one or two moles?
As hydrogen gas naturally occurs in a diatomic state, it is true that there is only one mole of naturally-occurring elemental hydrogen in answer one, but one mole of H2 is formed from 2 moles of H.
