## How many atoms are present in 9 grams of aluminium?

No. Of atoms of Al in 9 gram = 0.333× Avogadro no. =0.333×6.022×10^23=**2.005×10^23 atoms**.

## How many atoms are in 9 grams of aluminium and 0.8 grams of iron?

Explanation: of moles of atoms present in 9 grams of aluminium is 0.33 moles. mole of a substance contains 6.022×10 atoms/molecules so 0.014324 moles will contain 0.014324×6.022×10 atoms. i.e 0.086259×10 atoms of iron which is approximately equal to **86.259×10 atoms**.

## How many grams are in 9.0 moles of aluminum?

The molar mass of aluminium is 27 grams per mole. Therefore, 1 mole of aluminium will weigh 27 grams. Thus, the total number of moles in 9 grams of aluminium = **9g/27g**.

## How many atoms are in 1g of aluminum?

One mole of aluminum atoms has a mass of 26.98 grams, and contains **6.02×1023 atoms**.

## How many moles are in an atom?

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 will be there in 3 moles of Fe?

Answer: One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol.

## How many number of molecules are there in 22g of co2?

6.02*10^23 molecules equals 1 mole.

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

Therefore, **[2.41times 10{}**^text{2}] atoms/mol of Aluminum are present in $4$ mol of Aluminum.

## How many grams is 5 moles aluminum?

then, 5 moles of Aluminum (Al) = 5×27 = **135 grams**…

## How many moles are in 2 grams of Naoh?

240=**0.05**.

## How many atoms are in 27 grams of aluminum?

**13 atoms**. Hint: Mole is the unit for the number of atoms or molecules of a material. One mole is equal to the Avogadro’s number and each element has a different molar mass depending on the weight. It means 1 mole of aluminium contains ${ 27g }$ of aluminium.
