moles to atoms you multiply the number of moles by avogadros number
ex:
1.32 mol x (6.022 x 10^23 atoms)/mol
mass to atoms you multiply the mass (in grams) times the molar mass of the element or compound (ex: N 14.01 mols/gram) then times avogadros number once you have the moles.
ex:
45.6 g N x (14.01 mol/gram) x (6.022 x 10 ^23 atoms/mol)
if it's a compound instead of an element, find the molar mass of the compound (the molar masses of all the elements in it added up) and multiply by it.
-------------------------
Actually you are wrong, from mass to atoms you need to take the initial mass divide by the gram of the element that you are doing and multiply by the Avogadros number
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
The mass can be converted in energy: the equation of Einstein is: E= mc2.
To convert from grams to atoms, you need to use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the given amount of substance into moles and then multiply by Avogadro's number to get the number of atoms. To convert from mass (in grams) to the number of atoms, first find the molar mass of the substance, then divide the given mass by the molar mass to get moles, and finally multiply by Avogadro's number to obtain the number of atoms.
To convert grams of Cu to atoms, first calculate the molar mass of Cu from the periodic table (63.55 g/mol). Next, divide the given mass (12.54 g) by the molar mass to get moles of Cu. Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
To find the mass of 1.20x10^28 atoms of copper (Cu), you need to first calculate the molar mass of copper (Cu), which is approximately 63.55 g/mol. Then, convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23 atoms/mol). Finally, convert moles to kilograms by multiplying by the molar mass and dividing by 1000 to get the mass in kilograms.
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
To convert 1.5 grams of carbon to the number of carbon atoms, you would need to use Avogadro's number, which is the number of atoms in one mole of a substance (6.022 x 10^23 atoms/mol), and the molar mass of carbon (12.01 g/mol). By dividing the given mass of carbon (1.5 g) by the molar mass of carbon, you can convert the grams to moles, and then use Avogadro's number to calculate the number of carbon atoms.
Well, honey, to convert atoms to grams, you need to use the molar mass of copper. Copper has a molar mass of 63.55 g/mol. So, you multiply the number of atoms by the molar mass to get the mass in grams. In this case, it would be 2.11x10^24 atoms x 63.55 g/mol = your mass in grams. Easy peasy lemon squeezy!
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
To find the number of atoms in 0.0728 g of PCl3, you first convert the mass to moles using the molar mass of PCl3 (137.33 g/mol). Then, you use Avogadro's number (6.022 x 10^23) to convert moles to atoms. The number of atoms in 0.0728 g of PCl3 would be approximately 2.69 x 10^21 atoms.
To find the mass of 1.20x10^25 atoms of sulfur, you need to calculate the molar mass of sulfur and then convert the number of atoms to moles. The molar mass of sulfur is 32.06 g/mol. Once you have the number of moles, you can multiply it by the molar mass to find the mass of 1.20x10^25 atoms of sulfur.
To find the number of argon atoms in 1.5x10^2g of argon, we first need to determine the molar mass of argon. The molar mass of argon is approximately 39.95 g/mol. Next, we convert the given mass to moles by dividing by the molar mass. Finally, we use Avogadro's number (6.022x10^23) to convert moles to atoms. The number of argon atoms in 1.5x10^2g of argon would be approximately (1.5x10^2g / 39.95g/mol) x 6.022x10^23 atoms.
