## How many atoms are in 2.5 moles?

2.5 mol **16.02×1023 atoms**. M = (1.5 x 1024 atoms Timol.

## How many grams are in 2.5 moles of sodium?

And since we know that 1⋅mol of sodium has a mass of 22.99⋅g , we got a mass of 2.50⋅mol×22.99⋅g⋅mol−1=**57.5⋅g** with respect ot sodium.

## How many atoms are there in 1.5 moles of sodium?

We should get about **9.03 x 10^23 atoms** of sodium.

## How many atoms are there 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**.

## How many atoms are there in 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.

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

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

## How do you find number of atoms?

To calculate the number of atoms in a sample, **divide its weight in grams by the amu atomic mass from the periodic table**, then multiply the result by Avogadro’s number: 6.02 x 10^23.

## How many grams are there in 2.1 moles of sodium?

Hence, the number of grams of sodium is present in 2 moles is **46g** . Additional Information: The number 6.022×1023 is commonly referred to as the constant of Avogadro and is often denoted by the ‘ NA ‘ symbol.

## How many molecules are there in 2.5 moles of h2o?

Stefan V. **1.5×1024 molecules**.
