## How many atoms are in 2.5 moles of NaOH?

2.5⋅6.02⋅1023≈**1.5⋅1024 sodium atoms**.

## How many grams is 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 grams of NaOH are in 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.

## 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 formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## How many grams are there in 10 moles of sodium?

One mole of any substance is equal to the value of Avagadro number (6.023 x 10^{23}). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol. ∴ The mass of 10 moles of sodium sulphite = **1260 grams**.

## How many moles are in 4 grams of NaOH?

=**0.10** (approx.)

## What is the formula for moles?

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. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many moles is 5.69 g NaOH?

To change grams of a compound to moles of a compound. For example How many moles is 5.69 g of NaOH? **6.02 x 1023 molec**.

## How many moles are in 80g of NaOH?

= 80 / 40= **2 mol** .
