Answer:
0.1
Explanation:
Using Henderson-Hasselbalch equation
pH = pKa + log ( base / acid )
pH= 9.0 , pKa = 10.0
9.0 = 10 + log ( base / acid )
9 - 10 = log ( base / acid )
10⁻¹ = ( base / acid )
( base / acid ) = 0.1
Answer:
33 moles
Explanation:
The given chemical reaction is 2C₄H₁₀(g) + 13 O₂(g) → 10H₂O(g) + 8CO₂(g)
The number of moles of each reactant are as follows;
Butane, C₄H₁₀ = 2 moles of (g) + 13 (g) → 10H₂O(g) + 8CO₂(g)
Oxygen gas, O₂ = 13 moles
Water, H₂O = 10 moles
Carbon dioxide, CO₂ = 8 moles
The total number of moles, n = (2 + 13 + 10 + 8) = 33
∴ The total number of moles involved in the reaction, n = 33 moles.
