## How many atoms of sodium are in 3.25 moles of sodium?

of atoms = 3 × 6.022 × 10^23 = **18.066 × 10^23 atoms**.

## How many atoms are in 3g of sodium?

Answer. Mass of 1 mole of sodium is 2.3 g. 2.3 g of sodium gas contain 6×10^23 molecules. 2.3**×10^23 atom** .

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

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

## How many atoms are in a mole calculator?

Avogadro’s number is a very important relationship to remember: 1 mole = **6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number.

## How many atoms is 3 moles sodium?

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 a substance?

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to **6.02214179×1023 atoms**, or other elementary units such as molecules.

## How many atoms are in 3.0 moles of Sn?

There are **3×NA tin atoms** in 3.0 mol of tin metal, where NA is Avogadro’s number, 6.022×1023 mol−1 .

## How many atoms are in 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 does 2.0 moles represent?

According to Avogadro’s number, 1 mol of any substance contains 6.022 × 10^{23} particles. As a result, 2.0 moles of helium (He) represent 2.0 mol × 6.022 × 10^{23} = **1.2 × 10 ^{24} atoms**.

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

**2.4×1024 atoms**.

## How much is 3 moles NaOH?

It’s a 3.0 M solution so **1 litre of solution** contains 3 moles of NaOH. 250 ml of solution therefore contains 0.25 x 3 = 0.75 moles of NaOH. The molar mass of NaOH is 39.9971 g/mol, so 250 ml of this solution contains 0.75 x 39.9971 = 29.99 g, or if you round it up 30.0 g.

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

The mass of 3 moles of sodium chloride is thus **175.32 g**.
