What is the total mass contained in 2.00 moles of helium?
1 mole of helium weighs 4.0026 g. So 2 mole will weigh 8.0056 g.
What is the total number of atoms contained in 2.00 moles of helium?
This number is 12,044 280 171 4.10e23.
Convert 1.2 x 1024 atoms of helium to moles?
How many moles are there in 9.0333x1024 atoms of helium
How many moles are present in 205 g of helium?
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
How do you convert 26.7kg of helium into moles of helium?
6675 moles Moles = weight (in g) / atomic weight = 26700 g / 4 = 6675 moles
How many moles of Helium are in 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
What is the total mass contained in 2.00 moles of helium?
1 mole of helium weighs 4.0026 g. So 2 mole will weigh 8.0056 g.
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
0.46 divided by the formula weight of helium (4) 0.46/4=0.115 or 0.12 moles of Helium
How many moles of helium gas (he) are present in 7.2 liters of helium gas at standard conditions?
The number of moles of helium is 0,32.
What is the total number of atoms contained in 2.00 moles of helium?
This number is 12,044 280 171 4.10e23.
How many moles of Helium are present in 5.66 moles of H2O?
H2O or water doesn't have any helium in it.
How many grams are in 0.775 moles of helium?
The mass of helium equivalent to 0,775 moles is 3,102 g.
What is the mass in grams of 1.5 moles of helium?
The mass of 1,5 moles of helium is 6,003 903 g.
Convert 1.2 x 1024 atoms of helium to moles?
How many moles are there in 9.0333x1024 atoms of helium
How many moles are present in 205 g of helium?
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
How do you convert 26.7kg of helium into moles of helium?
6675 moles Moles = weight (in g) / atomic weight = 26700 g / 4 = 6675 moles
How many moles are present in 205g of helium?
To calculate the number of moles, you need to divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 g/mol. Therefore, the number of moles in 205g of helium would be 205g / 4g/mol = 51.25 mol.
