4.06 X 1025 molecules NaF (1 mole NaF/6.022 X 1023)
= 67.4 moles sodium fluoride
=====================
Quite a few. 6.32 X 10^25 atoms sodium (1 mole Na/6.022 X 10^23) = 105 moles of sodium
One mole is 6.022 × 1023 (or 602,200,000,000,000,000,000,000) bits of anything. You have 18.9 moles. Thus: 18.9 × (6.022 × 1023) = 1.138158 × 1025 (or 11,381,580,000,000,000,000,000,000) molecules Cl2.
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
1.30*1025
A mole of potassium consists of Avogadro's number of atoms. Therefore 6.85 X 1025 atoms comprises (6.85 X 1025)/(6.022 X 1023) or 114 moles, to the justified number of significant digits.
There are approx 2.05*1025 molecules.

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.
The equivalent is 154 moles.
20.4 MOLES OF PCl3
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
1.30*1025
The element magnesium does not form polyatomic molecules with specific numbers of atoms. Therefore, one mole ofmagnesium contains Avogadro's Number of atoms, and Avogadro's number is about 6.022 X 1023. Therefore, 1.48 X 1025 atoms contains (1.48/6.022) X10(25-23) or about 24.7 moles, to the justified number of significant digits.
A cup of coffee (200 cm3) contains about 1.5 * 1025 molecules.
The answer is 2,107749515.1025 molecules.
100 times Avogadro's Number = 6.022 X 1025.
