## How many mole molecules are in 8g oxygen?

The mass of oxygen is 8g. To find the number of molecules first, find the number of moles in the oxygen molecule. The number of moles in the oxygen molecule is 0.25moles.

## How many moles are in 1 kg of oxygen?

so,62.5 moles of oxygen have (6.022×10^23×62.5) molecules. Hence 1 kg of oxygen has (376.38×10^23) molecules.

## How many moles are there in 8g of he?

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.

## What is the number of oxygen molecules in 8g of O2?

Molar mass of oxygen gas= 32g. no. of moles in 8g = 8/32= 0.25 molesno. of particles(molecules) = 0.25 * 6.02 * 10^23 =1.5 *10^23.

## How many molecules are in 8 grams of O2?

= 1.5 x 1023 molecules contains 8 grams of O2.

## How many electrons are in 1 kg of oxygen mole?

Now , 1 mole of any compound = 6.022 x (10)^23 atoms. Therefore, 3.096 x (10)^26 electrons.

## What is KG mole?

One kg-mol (or one kilo mole) is the molecular mass of the substances expressed in kilogram. We know that in CGS system one g-mole of substances contain Avogadro no of particles (6. 023×1023) and in SI system one kg-mol substance contains Avogadro no of particles (6.

## How do I calculate moles?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.
