3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

## How many atoms are in 3 moles of sodium in a?

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

## How many atoms are in 3 moles?

Avagadro number is roughly 6.022 ×10^23 . So in 3 moles of carbon there are 18.066 ×10^23 atoms. Carbon has an atomic mass of approximately 12, and 1 mole of an atom weighs as much as the atomic mass of that element in grams.

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

Then, multiply the number of moles of Na by the conversion factor 6.02214179×10^{23} atoms Na/ 1 mol Na, with 6.02214179×10^{23} atoms being the number of atoms in one mole of Na (Avogadro’s constant), which then allows the cancelation of moles, leaving the number of atoms of Na.

## What is the mass of 3 moles of sodium atom?

Explanation: Sodium metal has a molar mass of 22.99⋅g .

## How many atoms are present in sodium?

We know that the atomic mass of sodium (Na) is equal to 23 grams. Now from the mole concept, we know that Gram atomic mass = 1 gm atom $ = 6.022 times {10^{23}}$ atoms. So, according to the mole concept, 23 grams of sodium (Na) contains $6.022 times {10^{23}}$ number of atoms.

## How many atoms does sodium have?

This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. Elements by themselves do not have a “number of atoms”- if you’re talking about the atomic number, it’s the number of protons (or electrons in a neutral atom) of an element.

## How much is 3 moles?

One mole of any substance is equal to its molar mass. 3 moles of water has a mass of 30g. similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=54 gram. It would constitute 3N molecules of water.

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

There are 1.806 x 1024 atoms in 3 moles of chromium. In one mole of any element, there is Avogadro’s number of atoms, which is 6.02 x 1023.

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

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 .

## How many atoms is a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many atoms are in 4 moles of sodium?

2.4×1024 atoms.

## How many atoms are in 2 moles of sodium?

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

## What is the mass of 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30. g with the right number of significant figures.

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

A mole is a unit of measurement, which equals 6.02 * 10^23. If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.
