Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
How much does a mole of an ideal gas weigh?
It weights the same as one times the molar mass in g/mol. It is NOT important to be ideal, it even needn't to be necessarily a gas, only the kind of compound is important.
Calculate the volume of dry hydrogen gas that would be produced by one mole of magnesium at standard temperature and pressure?
One mole of magnesium will react with two moles of hydrochloric acid to produce one mole of hydrogen gas. At standard temperature and pressure (STP), one mole of any gas occupies approximately 22.4 liters. Therefore, one mole of magnesium will produce 22.4 liters of hydrogen gas at STP.
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
A mole of anything has the same number of molecules as a mole of anything else. The why comes from the fact that this is the standard definition as agreed by scientists. We have to have standards for things to work. A mole of anything contains an Avagadro number of particles. That number is 6.022 x 1023
Given 1.00 mole of each what gases at STP which gas would have the greatest volume?
At STP (standard temperature and pressure), all gases have the same volume of 22.4 liters per mole regardless of their identity. Therefore, 1.00 mole of each gas would occupy the same volume of 22.4 liters.
How many gas particles are one mole of gas?
There would be 6.022 x 1023 gas paricles in one mole of that gas.
What is the mass of 1 mole of gas?
39.95 because that is the molar mass of Argon
What does avogadros law say about a gas at STP?
1 mole of gas at STP occupies 22.4 liters.
What is constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
What is the mole fraction of oxygen gas in air?
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
How many moles of bromine atoms in 1 mole of bromine gas Chemistry question need help with homework?
one mole of a substance is described as 6.02x1023 atoms of a substance so if one mole of bromide gas contains 6.02x1023 atoms then bromide gas will contain one mole. your question is a trick question as the gas is stated as containg one mole there fore it contains one mole of bromide atoms
What ia CNG?
Compressed natural gas
What is the volume of a mole of any gas at standard temperature and pressure?
The volume of a mole of any gas at Standard Temperature and Pressure (STP) is approximately 22.4 liters. This is known as the molar volume of a gas at STP and is a standard value used in gas calculations.
What is the constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
One mole of N2 gas at STP will occupy what volume?
22.4 L. At STP 1 mole of any gas will always be equal to 22.4 L.
If 1 mole of gas occupies 224 dm cubed then how many m cubed would 2263000 tons be?
There is one critical piece of information missing in the question, i.e. which gas are we talking about since different gas will have different molecular weight. In addition 1 mole of gas occupies volume of 22.4 dm3 at stp. This is equivalent to 22.4 L or 0.0224 m3 per mole of gas. Assuming the molecular weight of the gas Y is x g/mole, then the general solution is as followed: 2263000 tons of gas Y equal 226300*1016*1000g/(x g/mole)*(0.0224 m3/mole) equal 5.15022592e9/x m3 of gas Y
