Mass of Aluminum= 8.829 g
<h3>Further explanation</h3>
Given
Reaction
2Al + 6HCl → 2AlCl₃ + 3H₂
Required
mass of Aluminum
Solution
At STP, 1 mol gas = 22.4 L
For 11 L of Hydrogen :
= 11 : 22.4
= 0.491
From equation, mol ratio Al : H₂ = 2 : 3, so mol Al :
= 2/3 x mol H₂
= 2/3 x 0.491
= 0.327
Mass Aluminum(Ar=27 g/mol) :
= 0.327 mol x 27 g/mol
= 8.829 g

Answer:
200 lb•ft/s
Explanation:
From the question given above, the following data were obtained:
Force (F) = 2 tons
Time (t) = 5 mins
Height (h) = 15 ft
Power (P) =?
Next, we shall convert 2 tons to pound. This can be obtained as follow:
1 ton = 2000 lb
Therefore,
2 tons = 2 × 2000
2 tons = 4000 lb
Next, we shall convert 5 mins to seconds. This can be obtained as follow:
1 min = 60 s
Therefore,
5 mins = 5 × 60
5 mins = 300 s
Finally, we shall determine the power of the pump. This can be obtained as follow:
Force (F) = 4000 lb
Time (t) = 300 s
Height (h) = 15 ft
Power (P) =?
P = F × h / t
P = 4000 × 15 / 300
P = 60000 / 300
P = 200 lb•ft/s
Thus, the power of the pump is 200 lb•ft/s
