## How many atoms are in a mole of oxygen?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms.

## How many atoms of oxygen is present in 0.5 moles of oxygen?

(i)0.5 mole of oxygen gas. (ii) 3.011 x 1023 atoms of oxygen. (iii) 6.022 x 1024 molecules of oxygen. (Given atomic mass of 0 = 16u; No = 6.022 x 1023 per mole)

## What is the mass of 0.2 mole of oxygen atoms show calculation?

-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.

## How many grams are in 1 mole of oxygen?

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How many atoms are in a mole?

Avogadro’s Number and the Mole. The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.

## What is the weight of 0.5 mole of oxygen?

0.5 moles of O2 weighs 16 grams.

## How many atoms are in 3 moles of oxygen?

Explanation: A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .

Answer:- O has largest number of atoms. Was this answer helpful?

## What is the mass of 5 moles of oxygen atom?

5 moles of oxygen contains 180 grams of oxygen.

## What is the mole of 12 gram of oxygen gas?

Therefore, 12 g of oxygen gas has 0.375 moles.

## What is the mass of 0.2 mole of oxygen atoms Class 9?

9. What is the mass of : (a) 0.2 mole of oxygen atoms? (b) 0.5 mole of water molecules? Ans. ∴ 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g (b) 1 mole of water molecules = 18 g ∴ 0.5 mole of water molecules = 18 × 0.5 = 9 g 10.

## How many moles are in 50 grams of oxygen?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to 3 moles.

## How many moles are in 100g of oxygen?

The answer is 15.9994. We assume you are converting between grams Oxygen and mole. You can view more details on each measurement unit: molecular weight of Oxygen or mol The molecular formula for Oxygen is O. The SI base unit for amount of substance is the mole.
