## How many molecules are in 3 moles sodium?

To calculate atoms from moles, multiply given moles by 6.022×10^23 atoms/mol. 3 mol Na × (6.022×10^23 atoms Na/1mol Na) = **1.807×10^24 atoms Na**.

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

The molar mass of sodium chloride is 58.44 g/mole. To find the molar mass of 3 moles, multiply 58.44 by 3. The mass of 3 moles of sodium chloride is thus **175.32 g**.

## How many molecules are in a mole?

The mole is represented by Avogadro’s number, which is **6.022×10 ^{23} atoms** or molecules per mol.

## How many molecules is 2.0 moles?

Thus, if we have 1 mole of a molecule present, we have 6.022*10^23 of those molecules present. If we have 2 moles of a molecule present, we have **2*1.022*10^23** of that molecule present etc.

## How many atoms are in 3 moles?

No. of atoms = 3 × 6.022 × 10^23 = **18.066 × 10^23 atoms**.

## 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 oxygen molecules are in 3.00 moles of oxygen?

You have 3 moles, so there are **3×6.022×1023 oxygen molecules** .

## How do you find moles of NaCl?

One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = **58.44 g/mol**.

## How would you make a liter of a 3 molar solution of NaCl?

3 Molar solution means there are **3 moles of Na Cl** salt in 1 Liter. Molecular weight of Na Cl = 58.44. Hence, there are 3 * 58.44 gms in 1 Litre of water. So 1,074.68 ml or 1, 074.68 gms of water is mixed with 3 moles of Na Cl to make the 3 M solution.

## How do you find moles of molecules?

**Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number:**

- To go from moles to molecules, multiply the number of moles by 6.02 x 10
^{23}. - To go from molecules to moles, divide the numbers of molecules by 6.02 x 10
^{23}.

## How do you find molecules?

Determine the mass of the substance, and its molar mass. Divide the given mass by its molar mass to get moles, then multiply times 6.022×1023molecules1mol .

## How do you find moles from molecules?

Calculate he number of moles you have by taking the **Mass / molar mass**. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.
