10 g platinum is equal to 0,05 moles.
The answer is 1,594 mol.
To find the number of moles, you need to divide the mass of the substance by its molar mass. The molar mass of platinum is 195.08 g/mol (rounded to two decimal places). Therefore, for 0.0034 g of platinum: 0.0034 g / 195.08 g/mol ≈ 0.000017 moles of platinum.
2,89 moles of aluminium contain 17,40398707673.1023 atoms.
The standard atomic weight of platinum is 195,084 g.195,084 g-------------------------------1 mol250 g-------------------------------------x molx = 250/195,084 = 1,28 mol platinum
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.
To find the number of moles of platinum in 10g, divide the mass by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol. Therefore, there are 0.051 moles of platinum in 10g.
The answer is 1,594 mol.
To find the number of moles, you need to divide the mass of the substance by its molar mass. The molar mass of platinum is 195.08 g/mol (rounded to two decimal places). Therefore, for 0.0034 g of platinum: 0.0034 g / 195.08 g/mol ≈ 0.000017 moles of platinum.
To determine the number of atoms in 97.6g of platinum, you first need to calculate the number of moles of platinum using its molar mass (195.08 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of platinum to atoms. This calculation will give you the total number of atoms in 97.6g of platinum.

That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
Approx. 0,5 moles.
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
2,2 moles of plutonium: 13,248711938.1023 atoms.
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms
