Answer:
The "unit" remaining after conversion is atoms.
This is a way to calculate the number of atoms, in an specific mass.
Explanation:
When you have a mass, multiplying the molar mass, "grams" are cancelled, so you finally obtained, number of moles.
Moles . atoms/mol, cancel the word mol so you will find out a number of atoms, present at the mass from, the begining.
For example, how many atoms are in 10 g of NaCl
Molar mass NaCl = Na mass + Cl mass
23 + 35.45 = 58.45 g/m
10 g . 1 / 58.45 mol/g . NA/ 1 mol = 3.42x10²⁰ atoms
NA = Avogadro number
Answer:
≈29.94 [°C].

Answer:
Explanation:
Ionic bond
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Answer:
Explanation:
In one mole of carbon, there are 6.02×10^23 atoms. So in two moles, there will be twice that: 1.204×10^24
