Answer:

#6  8.67x10²⁴ atoms

#7  

1. Atom

2. Formula unit

3. Molecule

4. Ion

Explanation:

#6 First we calculate how many carbon moles are there in 7.00 moles of C₂F₂, keeping in mind that there are 2 C moles per C₂F₂ mol:

  • 7.00 mol C₂F₂ * 2 = 14.00 mol C

As for carbon dioxide, there are 0.400 C moles in 0.400 moles of CO₂.

We calculate the total number of C moles:

  • 14.00 mol + 0.400 mol = 14.4 mol C

Finally we calculate the number of atoms in 14.4 C moles, using Avogadro's number:

  • 14.4 mol * 6.023x10²³ atoms/mol = 8.67x10²⁴ atoms

#7

  • 1. Radon - Atom (Ra)
  • 2. Formula unit (It is a crystalline solid, BaBr₂)
  • 3. Molecule (NH₃)
  • 4. Ion (It has a formal charge, +2)
