The conversion of particles from grams to atoms can be determined as below:Suppose you have 10 gram of carbon. Now, it should be converted in terms of atoms. We know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole. Also, the Avogadro constant is 6.02 x 10 23. So, the

### How many atoms are in 6.00 grams of carbon? Study

In order to calculate the number of atoms in 6.00 g of carbon, we first need to calculate the moles of carbon present. This is done by using the How many grams of sodium will have the same number of The difference in the mass of 100 each mole of sodium atoms and sodium ions is 5.48002 g. Calculate the mass of an electron from the above data.

### How to Find the Number of Atoms in an Element Sciencing

Apr 26, 2018 · To calculate the number of atoms in a sample, you need to find how many moles of the element the sample contains. A mole is a unit chemists use. It's equal to Avogadro's number (6.02 X 10 23) of atoms. By definition, the weight of one mole of an element (its molar mass) is equal to its atomic weight in grams.
