11)
Answer:
9.08 mol
Given data:
Number of moles of P₂O₅ = ?
Number of moles of O₂ = 22.7 mol
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of P₂O₅ with O₂.
O₂ : P₂O₅
5 : 2
22.7 : 2/5×22.7 = 9.08
12)
Answer:
7 mol
Given data:
Number of moles of P₂O₅ = ?
Number of moles of P = 14 mol
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of P₂O₅ with P.
P : P₂O₅
4 : 2
14 : 2/4×14 = 7
13)
Answer:
76.25 mol
Given data:
Number of moles of P = 61 mol
Number of moles of O₂ react = ?
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of P with O₂.
P : O₂
4 : 5
61 : 5/4×61 = 76.25
14)
Answer:
1.25 mol
Given data:
Number of moles of P₂O₅ = 0.5 mol
Number of moles of O₂ needed = ?
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of P₂O₅ with O₂.
P₂O₅ : O₂
2 : 5
0.5 : 5/2×0.5 = 1.25
15)
Answer:
20 mol
Given data:
Number of moles of P₂O₅ = 8 mol
Number of moles of O₂ needed = ?
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of P₂O₅ with O₂.
P₂O₅ : O₂
2 : 5
8 : 5/2×8 = 20
16)
Answer:
12 mol
Given data:
Number of moles of silver made = ?
Number of moles of Ag₂O = 6 mol
Solution:
Chemical equation:
2Ag₂O → 4Ag + O₂
Now we will compare the moles of Ag with Ag₂O .
Ag₂O : Ag
2 : 4
6 : 4/2×6 = 12
17)
Answer:
25 mol
Given data:
Number of moles of silver made = ?
Number of moles of O₂ produced = 6.25 mol
Solution:
Chemical equation:
2Ag₂O → 4Ag + O₂
Now we will compare the moles of Ag with O₂ .
O₂ : Ag
1 : 4
6.25 : 4×6.25 = 25
18)
Answer:
9.8 mol
Given data:
Number of moles of silver made = ?
Number of moles of O₂ produced = 2.45 mol
Solution:
Chemical equation:
2Ag₂O → 4Ag + O₂
Now we will compare the moles of Ag with O₂ .
O₂ : Ag
1 : 4
2.45 : 4×2.45 = 9.8
19)
Answer:
4.4 mol
Given data:
Number of moles of silver oxide required = ?
Number of moles of O₂ produced = 2.2 mol
Solution:
Chemical equation:
2Ag₂O → 4Ag + O₂
Now we will compare the moles Ag₂O of with O₂ .
O₂ : Ag₂O
1 : 2
2.2 : 2×2.2 = 4.4
20)
Answer:
1.5 mol
Given data:
Number of moles of silver oxide required = ?
Number of moles of O₂ produced = 0.75 mol
Solution:
Chemical equation:
2Ag₂O → 4Ag + O₂
