How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
How do you convert 26.7kg of helium into moles of helium?
To convert grams to moles, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 26.7kg of helium is equal to 26,700g, which would be 6,675 moles of helium.
What is the mass in grams of 5.40 moles of helium?
For this you need the atomic mass of He. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.5.40 moles He × (4.00 grams) = 21.6 grams He
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.
How many moles does g of helium he contain?
To calculate the number of moles of helium in a given mass (g), you can use the formula: [ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ] The molar mass of helium is approximately 4.00 g/mol. So, if you have a specific mass of helium, divide that value by 4.00 g/mol to find the number of moles.

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.
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 5.40 moles of helium?
For this you need the atomic mass of He. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.5.40 moles He × (4.00 grams) = 21.6 grams He
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.
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.

How many moles are present in 205 g of helium?
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
What is the mass of 18.8 moles of helium atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
How many moles are present in 0.12g of helium?
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
