Atoms To Grams

One mole consists of Avogadro number of atoms. If you know the quantity of mole, it can be converted into grams and vice versa. The formula for moles to grams is given. Example 1 – Calculate the mass in grams of 3.6 mol of H 2 SO 4. Look for the atomic masses of hydrogen, sulfur and oxygen. Grams to Atoms Calculator is a free online tool that displays the conversion from grams to atoms for the particle. BYJU’S online grams to atoms calculator tool makes the conversion faster and it displays the conversion to atoms in a fraction of seconds. How to Use Grams to Atoms Calculator? The amount of atoms you have depends on what element youre working with. So first you need to find a way to convert grams of carbon to how many moles of carbons that is. You have probably done this already. Think molar mass. Once you know the moles of atoms that you have, you can determine the amount of atoms using avogadros constant.

The last step we are going to address in this particular conversion map is the conversion to atoms. Converting between atoms and molecules is much easier than the steps that we have done before. However, it seems to many students because of that they get thrown off and have a difficult time. This conversion is all about how many of each element are in a particular substance. Check out the examples below for a more detailed explanation.

If we wanted to say how many atoms of Br are in NBr3 then we would say 3. Now the only difference with these conversions is we have to turn that statement into a ratio between the molecule (NBr3Nordvpn ios manual. ) and the atom (Br).

1 NBr3
3 Br


3 Br
1 NBr3

We can also do this for molecules that have only one atom of one element. It just looks kind of silly so most teachers and books will not show it to you. Lets say we had the molecule Ni. How many atoms of Ni are in the molecule of Ni? 1 atom of Ni for every 1 molecule of Ni.

1 Ni
1 Ni


1 Ni
1 Ni

Now the above may look trivial and painfully obvious but believe it or not a lot of students run into problems with the above ratio and it is nothing to be ashamed of. It is hard for people to describe and therefore it is hard for students to understand correctly. In these special cases where there is only 1 atom per 1 molecule then you don’t really need to do any extra math steps. However, I will show you to them in my demonstrated examples to make sure everyone understands what is going on.

This last step in our conversion map is the arrow furthest to the right (the purple text).

VIDEO Converting Between Grams and Atoms Demonstrated Example 1: If you have 12g of CH4 how many atoms of hydrogen do you have? You will need the periodic table for this question.

Step 1:

What information does the problem give you?

Answer: 12g CH4

Step 2:

What units does the question ask for?

Answer: ? atoms H

Step 3:

How many conversions must we do?

Answer: Look at the conversion map. We pass through 3 arrows when we go from Grams —> Moles —> Molecules —> Atoms. 3 arrows = 3 conversion

Step 4:

How do we set up the problem?

Answer: First box is info given, next 3 boxes are the 3 conversion, last box (fifth box) is what the question asked for.

12 g CH4atoms H

Step 5:

What is the first conversion?

Answer: molar mass (grams to mole ratio) of CH4found on the periodic table

Step 6:

What is the molar mass of CH4?

Answer: about 16 g/ 1 mol

Step 7:

How do we set that up in the conversion?

Answer: units first, set up the units that need to cancel out (in red)

12 g CH41 molatoms H
16 g

Step 8:

What conversion should we use next?

Answer: Avogadro’s number (moles to molecules ratio) found on the conversion map. 6.022 * 1023 molecules / 1 mol

12 g CH41 mol6.022 * 1023 molecatoms H
16 g1 mol

Step 9:

What conversion should I use next?

Answer: the atom to molecule ratio (4 H to 1 CH4)

12 gCH41 mol6.022 * 1023molec4 atoms H =atoms H
16 g1 mol1 molec CH4

Step 10:

How do I know when I am done with the conversions?

Answer: All other units but the ones in the answer are crossed out through cancellation. For this example atoms and H remain not crossed out.

12 gCH41 mol6.022 * 1023molec4 atoms H =atoms H
16 g1 mol1 molecCH4

Step 11: Simplify

1216.022 * 10234 atoms H =atoms H

Step 12:

How do I calculate?

Answer: (12 * 6.022 * 1023 *4) / (16) = 1.81 * 1024

Step 13:

COMPLETE ANSWER: 1.81 * 1024 atoms of H
