D) An atom with 4 protons, 3 neutrons, and 3 electrons
Answer:
24 atoms
Explanation:
The formula of the compound is C₇H₁₆O
The number of atoms that makes up one molecule of this compound are:
7 carbon atoms
16 hydrogen atoms
1 oxygen atom
The total number of atoms = 7+16+1 = 24 atoms

Answer:
- 5.15×10²⁴ molecules of sulfur dioxide
- 3.63×10²³ molecules of carbon monoxide
- 6.02×10²³ molecules of ammonia
Explanation:
We begin from the relation that 1 mol of molecules contains NA of molecules
NA = 6.02×10²³
Now, we make rules of three:
1 mol has 6.02×10²³ molecules, therefore:
8.55 moles of SO₂ must have (8.55 . NA) / 1 = 5.15×10²⁴ molecules of dioxide
0.603 moles of CO must have (0.603 . NA) / 1 = 3.63×10²³ molecules of monoxide
Avogadro's Number of molecules of NH₃ are 6.02×10²³ molecules of ammonia
