## How many atoms does 1 mole of uranium have?

One mole of U238 ( 6.022 X 10^23 atoms) is 238 grams; one mole of U235 is 235 grams.

## How many atoms does 1 mole of nitrogen have?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms. Also, one mole of nitrogen atoms contains 6.02214179×1023 nitrogen atoms. The number 6.02214179×1023 is called Avogadro’s number (NA) or Avogadro’s constant, after the 19th century scientist Amedeo Avogadro.

## How many atoms are in 1g of gold?

Answer: Atomic weight of the Gold (Au) is = 196.97 (197g apprx.) That means 6.022X10^23 atoms weigh 196.97 g.

## How many atoms are in u235?

So Uranium-235 contains 6.02214179×1023 / 235 = about 2.5626135×1021 atoms per gram.

## How many atoms are in a human body?

Suzanne Bell, an analytical chemist at West Virginia University, estimates that a 150-pound human body contains about 6.5 octillion (that’s 6,500,000,000,000,000,000,000,000,000) atoms. The vast majority of them are hydrogen (humans are almost entirely water, which comprises two hydrogen atoms and an oxygen).

## How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

## How many atoms are in h2o?

An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O.

## What is the total number of atoms in 1.0 mole of co2?

Let’s consider the carbon dioxide molecule. We know it has the formula CO2, and this tells us that: 1 mole carbon dioxide contains 6.02 x 1023 molecules. 1 mole of carbon atoms per mole of carbon dioxide = 6.02 x 1023 carbon atoms.

## How many moles are in 1kg of uranium 235?

The number of 235U atoms in 1.00 kg is Avogadro’s number times the number of moles. One mole of 235U has a mass of 235.04 g; thus, there are (1000 g)/(235.04 g/mol) = 4.25 mol.
