How many moles are in 16g of he?

How many moles are in 16g of he?

4 moles
The correct answer is 24.09 × 1023. 1 mole helium = 6.023 x 1023 atoms. 1 mole helium = 4g. So, 16 g helium = 16/4 moles = 4 moles.

How many moles are in 12 grams of helium?

The answer is 4.002602. We assume you are converting between grams Helium and mole.

How do you calculate grams of an element?

You look up the atomic mass of each of the elements in the formula, multiply it by the number of atoms of that element in the compound and add it to all the others. This gives you the mass, in grams, of one mole of the molecule.

How many moles are in 8g of he?

Two moles
Helium is a monatomic, so, the number of atoms in the He element is one. Two moles = $\,1.204 \times {10^{24}}$atoms. So, two moles or we can say eight gram of He contains $1.204 \times {10^{24}}$atoms.

How many moles are in 4 moles of he?

Answer: 1 mole of Helium = weight of helium/4weight of helium= 1*4=4 grams 1 mole of Helium contains 6.023*10>23 (Avogadro Number)atoms.

How many atoms are there in 16 moles of helium?

of atoms in 16 moles of helium. Hence there are 9.635 X 1024 atoms of He in 16 moles of He.

How do you calculate grams from atoms?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.

How many moles are in 20.0 grams?

There are 5.00 moles He in 20.0 g He.

How many grams are in 12 moles of he?

Just under 50⋅g .

How many moles are in 1g of he?

molecular weight of He or mol. The SI base unit for amount of substance is the mole. 1 grams He is equal to 0.24983748071879 mole. Note that rounding errors may occur, so always check the results.

How do you convert grams to moles in chemistry?

n = 5988 g / 18.015 g/mol = 332.4 mol. You can always use our grams to moles calculator to check the result! Knowing how to convert grams to moles may be helpful in numerous chemical tasks, e.g., finding the mole fraction of a solution.

How many molecules are there in 16 grams of oxygen gas?

In other words, 1 mole of oxygen would contain molecules. Here, we are given with 16 g of oxygen. The number of molecules in 16 gm of oxygen are 0.5 (= 16/32 moles). Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^ (23) = 3.012 x 10^ (23) molecules.

How many moles are in 5988 grams?

It’s easier to work with grams, so convert the mass: 5.988 kg = 5988 g. As you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol. You can always use our grams to moles calculator to check the result!
