There are 2.06 x 10²⁴ atoms
<h3>Further explanation
</h3>
The mole is the number of particles (atoms, molecules, ions)contained in a substance
1 mol = 6.02.10²³ particles
Moles can also be determined from the amount of substance mass and its molar mass
Uh i think it is a balance combustion reaction not entirely sure tho
Answer:
The answer to your question is 0.4 moles of Oxygen
Explanation:
Data
Octane (C₈H₈)
Oxygen (O₂)
Carbon dioxide (CO₂)
Water (H₂O)
moles of water = ?
moles of Oxygen = 1
Balanced chemical reaction
C₈H₈ +10O₂ ⇒ 8CO₂ + 4H₂O
Reactant Element Products
8 C 8
8 H 8
20 O 20
Use proportions to solve this problem
10 moles of Oxygen ----------------- 4 moles of water
1 mol of Oxygen ------------------ x
x = (4 x 1) / 10
x = 4 / 10
x = 0.4 moles of water
