First you start by finding moles, 5.15x10^21 / 6.02x10^23=.0088555 , now you find the mass. .00799mol x 195.08 g/mol=1.67 grams
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.
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.
Platinum is a rare element too. Atomic number of platinum is 78.
To find the mass of 0.48 moles of platinum, you would multiply the number of moles by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol, so the mass of 0.48 moles of platinum would be 0.48 moles * 195.08 g/mol ≈ 93.62 grams.
Platinum is a metal element. Atomic mass of it is 195.08.
The mass of 4.9810e21 platinum atoms is 0,000 042 g.
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.
Re-think your question. You can't have 5.061021 atoms. Maybe you mean grams or moles?
Well, in 1 mole of platinum there are 6.022 x 10^23 atoms. Furthermore 1 mole of platinum weighs approximately 0.1951 Kg. Therefore, the mass of two atoms of platinum is: 2(0.1951/6.022 x 10^23) = 6.48 x 10^-25 Kg (2 sig. fig)Or - 0.00000000000000000000000648 KgP.S. I am a fag.
If the chemical composition of the sample is known, then the answer is yes. However, equal masses of platinum and magnesium, for example, contain quite different numbers of atoms, because the atomic mass of platinum is much higher than that of magnesium.
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, and ductile metal that is part of the platinum group of metals. Platinum is primarily composed of platinum atoms bound together through metallic bonding.
Platinum is a metal element. Atomic mass of it is 195.
It's 97g/195.1g Pt = .497 .497 x 6.022x10^23= 2.993 mols/atom.
Platinum has the atomic weight (not mass) 195,084.
Platinum is a meta element. Atomic mass of it is 196.
Platinum contains 117 neutrons and the atomic number for platinum is 17.
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.
