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
What else can I help you with?
What has more mass one mole of helium or one mole of lead?
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
What has the most atoms one mole of gold helium or lead?
1 mole atoms of all atoms of any element will always have the same number of atoms and will be equal to 6.023 x 1023 atoms. However the weight will vary. 1 mole = 4 g of Helium or 197 g of gold or 207 g of lead
What is the number of atoms in 1.5 moles of helium if you calculate it?
There are 9.03 x 10^23 atoms in 1.5 moles of helium. This is because 1 mole of any substance contains Avogadro's number of atoms or molecules (6.022 x 10^23), so 1.5 moles would contain 1.5 times that number.
What is the total number of atoms contained in a 1.00 mole sample of helium?
The total number of atoms contained in a 1,00 mole sample of helium is 6,022 140 857.10e23.
How many helium atoms are in a millimole of helium?
So, in a mole of anything, there are 6.022x10^23 molecules or atoms. There are 1000 millimoles in a mole, so 6.022x10^23/1000 is 6.022x10^20 atoms.
What contains more molecules a mole of lead or a mole of carbon?
They both have the same number of atoms. The weight is different
What has more mass one mole of helium or one mole of lead?
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
What has the most atoms one mole of gold helium or lead?
1 mole atoms of all atoms of any element will always have the same number of atoms and will be equal to 6.023 x 1023 atoms. However the weight will vary. 1 mole = 4 g of Helium or 197 g of gold or 207 g of lead
What is the number of atoms in 1.5 moles of helium if you calculate it?
There are 9.03 x 10^23 atoms in 1.5 moles of helium. This is because 1 mole of any substance contains Avogadro's number of atoms or molecules (6.022 x 10^23), so 1.5 moles would contain 1.5 times that number.
What is the total number of atoms contained in a 1 mole sample of helium?
In one mole of helium, there is 6.02 x 10*23 atoms. In 1 mole of any substance, it contains 6.02 x 10*23 particles of that substance. This number (6.02 x 10*23) is known as Avogadro's number or Avogadro's constant.
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
Can a mole represent a molecule?
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
How many H2O molecules are in a mole of water molecules?
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
What is the total number of atoms contained in a 1.00 mole sample of helium?
The total number of atoms contained in a 1,00 mole sample of helium is 6,022 140 857.10e23.
How do you calculate molecules to moles?
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
How many helium atoms are in a millimole of helium?
So, in a mole of anything, there are 6.022x10^23 molecules or atoms. There are 1000 millimoles in a mole, so 6.022x10^23/1000 is 6.022x10^20 atoms.
Are molecules per mole a unit for avogadro's number?
No, the unit is "per mole". The number could be atoms or molecules but that is not part of the unit.
