Why can you divide atoms?
with a tiny razorblade
How many moles of atoms are in 450000000000000000000000 atoms of Cu?
Divide that number of atoms by 6.02x10^23 atoms/mole
How can you calculate no of moles from no of atoms?
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
How many moles of Na contain 7.88x1021 atoms of Na (to find moles, divide atoms by Avogadro's number)?
0.013089701
Can a atom divide into smaller particles?
Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Atoms can undergo nuclear reactions, such as fission or fusion, which can split the nucleus into smaller particles. However, in normal chemical reactions, atoms do not divide into smaller particles.
Do atoms get destroyed?
Atoms can be destroyed by various methods, the most commonly known example is a nuclear weapon detonating.
How many atoms of bromine will you multiply to get moles of bromine?
To convert atoms of bromine to moles of bromine, you would need to divide the number of atoms by Avogadro's number (6.022 x 10^23). So, to get moles of bromine, you would divide the number of atoms by Avogadro's number, not multiply.
How many moles are in hydrogen atoms?
There is 1 mole of hydrogen atoms in 6.022 x 10^23 atoms.
How many atoms are in 774 torr?
The unit torr is a measure of pressure, not of atoms. So, there are no atoms in 774 torr.
How do you do mass to particles?
By particles, I assume you mean atoms. Firstly, you divide mass by molecular mass to get moles. Then multiply moles by avagadros number to get amount of atoms
What percentage of hydrogen is in C2O6H12?
There are 6 hydrogen atoms in C2O6H12. To calculate the percentage of hydrogen in C2O6H12, divide the number of hydrogen atoms by the total number of atoms in the compound (which is 20). So, 6/20 = 0.3 or 30%.
If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
To find the percentage of copper-63 atoms in the sample, first add the number of copper-63 and copper-65 atoms together (1.76E4 + 7.88E3). Then, divide the number of copper-63 atoms by the total number of atoms and multiply by 100 to get the percentage. In this case, the percentage of copper-63 atoms in the sample is approximately 69.0%.
