Answer:
145.97×10²³ atoms
Explanation:
Given data:
Number of moles of CO₂ = 8.08 mol
Number of atoms of CO₂ = ?
Solution:
1 mole of CO₂ contain 1 mole C atom.
8.08 mole contain 8.08× 1 = 8.08 mole of C atom.
1 mole of CO₂ contain 2 moles of O atom.
8.08mole contain 8.08×2 = 16.16 mole of O atom.
Total number of moles of atoms = 8.08 mole + 16.16 mole
Total number of moles of atoms = 24.24 mol
Number of atoms of CO₂:
1 mole of any substance contain 6.022×10²³ atoms.
24.24 mol ×6.022×10²³ atoms / 1 mol
145.97×10²³ atoms
Answer:
Explanation:
Hello.
In this case, we first compute the volume of the pool via:
Then, since the density is defined as the mass divided by the volume, we compute the mass as follows:
Best regards.
