The total mass of four moles of helium (He) is 16.0104 grams.
What is the mass of 4.5 moles of helium?
The symbol for helium is He, and the symbol for grams is g. Therefore, 4.5 moles of helium to grams is the same as 4.5 moles of He to grams, 4.5 moles of helium to g, and 4.5 moles of He to g. Furthermore, the atomic mass of helium is 4.00260. That means that one mole of helium weighs 4.00260 grams (4.00260 g/mol).
How many moles are in 4 grams of helium?
If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams. We can use the molar mass as a conversion factor.
What is the mass of 4 moles?
(b) The mass of 4 moles of aluminium atoms is (4×27)g=108 g.
What is the mass of 2.0 moles of helium atoms?
The molar mass is “4.002602 g/mol”. Socratic.
What is the mass of helium gas?
Helium Gas was first detected in sun. It is available abundantly and is the second lightest gas seen. 4.00g / mol is the molar mass of helium.
What is the volume of 1 mole of helium?
A pressure of one atmosphere and a temperature of 0°C is known as standard temperature and pressure (STP). Under these conditions, one mole of any gas takes up a volume of 22.4 liters. This information allows us to convert between liters and moles for gases at STP. At STP, we have 46.2 liters of helium.
