How many moles of pottassium are represented by 6.85x1025 potassium atoms?
To find the number of moles, you first need to recognize that 6.022 x 10^23 atoms make up one mole (Avogadro's number). Thus, divide 6.85 x 10^25 atoms by Avogadro's number to get the number of moles. Therefore, the number of moles of potassium in this case would be 11.4 moles.
How many moles of He are 1.20 x 1025 atoms He?
In order to find how many Moles of He are 1.20 x 1025 atoms of He, you need to divide 1.20 x 1025 atoms by the Avagadro's number (6.022 x 1023) The answer is 19.9 moles of He.
How many grams of oxygen will be in 2 moles of pottassium dichromate?
The answer is 224,141 grams oxygen.
How many molecules of carbon dioxide gas are there in 34 moles?
There are approx 2.05*1025 molecules.
How many moles are represented by 32.50 g Mg?
how many moles are represented by 1.51 x 10^24 atoms Pb
How many electrons are in 9.00 moles of Carbon?
9.00 moles carbon (6.022 X 1023/1 mole carbon)(6 electrons/1 atom carbon) = 3.25 X 1025 electrons in 9.00 moles carbon ============================
How many moles of PCl3 contain 3.68 1025 chlorine atoms?
To find the number of moles of PCl3, you need to first calculate the number of moles of Cl atoms in 3.68 * 10^25 atoms. There are 3 Cl atoms in each molecule of PCl3, so you divide the number of Cl atoms by 3 to get the number of moles of PCl3.
How many moles of He are 1.20 x 1025 atoms?
The element helium does not technically have "moles", because its atomsdo not form any chemical bond with other helium atoms. Its formula unit is a single atom. Avogadro's Number, the number of formula units in a gram atomic mass, is about 6.022 X 1023. Therefore, 1.20 x 1025 atoms constitutes (1.20 X 1025)/(6.022 X 1023) or about 19.9 formula masses, to the justified number of significant digits.
How many moles are in 5.0 x 1025 atoms of iron?
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
How many electrons is in the outer shell of pottassium?
1
In the formula for sodium phosphate Na3PO4 how many moles of sodium are represented?
There are 3 moles of sodium represented in one mole of sodium phosphate (Na3PO4). This is because the subscript 3 in Na3PO4 indicates that there are 3 sodium ions for every molecule of sodium phosphate.
How many moles are in 4.06 x 1025 molecules of sodium fluoride?
To find the number of moles in 4.06 x 10^25 molecules of sodium fluoride, you would divide the number of molecules by Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol. Therefore, 4.06 x 10^25 molecules / 6.022 x 10^23 molecules/mol ≈ 67.5 moles of sodium fluoride.
