In one mole of C₂HBrClF₃, there are three fluorine (F) atoms. Therefore, to find the total number of F atoms in 12.15 mol of C₂HBrClF₃, you multiply the number of moles by the number of F atoms per mole: (12.15 , \text{mol} \times 3 , \text{F atoms/mol} = 36.45 , \text{F atoms}). Thus, there are 36.45 moles of F atoms in 12.15 mol of C₂HBrClF₃.

How many atoms of phosphorus are in 8.90 mol of copperII phosphate?
To find the number of phosphorus atoms in 8.90 mol of copper(II) phosphate (Cu₃(PO₄)₂), we first identify that each formula unit contains 2 phosphorus (P) atoms. Thus, in 8.90 mol of copper(II) phosphate, the total number of phosphorus atoms is calculated as follows: 8.90 mol × 2 P/mol = 17.8 mol of phosphorus atoms. To convert moles to atoms, we multiply by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol): 17.8 mol × (6.022 \times 10^{23}) atoms/mol ≈ (1.07 \times 10^{24}) phosphorus atoms.
How many argon (Ar) atoms are there in 1.5 102 g of argon?
To find the number of argon atoms, we first need to determine the molar mass of argon: 39.95 g/mol. Next, we convert the given mass to moles using the molar mass: 1.5 x 10^2 g / 39.95 g/mol = 3.75 mol. Finally, we use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 3.75 mol x 6.022 x 10^23 atoms/mol ≈ 2.26 x 10^24 argon atoms.
