How many moles are in 14.5 cm3 of platinum. The density of platinum 21.45 gcm3?
The answer is 1,594 mol.
How many moles are in 0.0034 g platinum?
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.

How many moles are in 0.0034 g platinum?
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.
How many atoms are contained in 97.6g 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.

How many number of moles are in al metal cube?
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
