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.
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
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 grams are in 0.775 moles of helium?
The mass of helium equivalent to 0,775 moles is 3,102 g.
How many moles in 6.071grams of helium?
To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
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.
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 does 2 moles of helium equal?
2 moles equals 8 g of helium or 12.046 x 1023 atoms
What is the mass of 10.7 moles of He?
The molar mass of helium (He) is approximately 4 g/mol. To find the mass of 10.7 moles of helium, you would multiply the number of moles by the molar mass: 10.7 moles * 4 g/mol = 42.8 g. Therefore, the mass of 10.7 moles of helium is 42.8 grams.
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
How many grams does 3.0 moles of He gas weigh?
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
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.
