To find the number of atoms in 11.8 g of lithium, you need to first calculate the number of moles of lithium present using the atomic mass of lithium (6.941 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
The gram Atomic Mass of lithium is 6.941; this is the amount of lithium that contains Avogadro's Number of atoms. Therefore, in 18.7 g of lithium, there will be (18.7)/(6.941) times Avogadro's Number of atoms, or about 1.62 X 1024, to the justified number of significant digits.
How many lithium atoms are in 10.56 g of lithium
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
To calculate the number of atoms in a sample of lithium, you first find the moles using the molar mass. Lithium's molar mass is approximately 6.94 g/mol. Then, use Avogadro's number (6.022 x 10^23) to convert moles to atoms.

How many lithium atoms are in 10.56 g of lithium
To find the number of lithium atoms, you would need to know the molar mass of lithium (6.94 g/mol) and then use the formula: Number of atoms = (0.01456 g / 6.94 g/mol) * Avogadro's number Avogadro's number is 6.022 x 10^23 atoms/mol.
54,9 g LiClO contain 16,9866.10e23 molecules.
To calculate the mass of 9.44x10^23 atoms of lithium, you can use the molar mass of lithium, which is approximately 6.94 g/mol. Divide the number of atoms by Avogadro's number to get the number of moles, then multiply by the molar mass to get the mass in grams.
To determine the number of atoms in 12.7 grams of lithium, you need to first calculate the number of moles using the molar mass of lithium (6.94 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert from moles to atoms.
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
To find the number of moles in 1.9 g of lithium, you need to divide the mass of lithium by its molar mass. The molar mass of lithium is approximately 6.94 g/mol. So, 1.9 g / 6.94 g/mol ≈ 0.274 moles of lithium.
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
Well, honey, if we're talking about lithium (Li) and you've got 55.2 grams of it, you're looking at approximately 7.4 x 10^23 atoms. That's a whole lotta Li atoms in your hands. Hope you've got a plan for all that atomic power!
I assume you mean 97.9 grams lithium. 97.9 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 8.49 X 10^24 atoms of lithium ---------------------------------------
