Photosynthesis in green plants during which CO2 is absorbed to form glucose
Answer:
The answer to your question is 5.529 x 10²⁴ molecules of H₂O
Explanation:
4NH₃ + 5O₂ ⇒ 4NO + 6H₂O
6.12 mol ? molecules
Rule of three (proportions)
4 mol of NH₃ ------------------- 6 mol of H₂O
6.12 mol of NH₃ --------------- x mol of H₂O
x = (6.12 x 6) / 4
x = 36.72 / 4
x = 9.18 mol of H₂O
1 mol of H₂O ------------------ 6.023 x 10²³ molecules
9.18 mol of H₂O ------------- x
x = (9.18 x 6.023 x 10²³) / 1
x = 5.529 x 10²⁴ molecules
<span>Fe atomic mass = 55.86
* 1 = 55.86
Cr atomic mass = 52
*2 = 104
O atomic mass = 16
* 4 = 64
Total molecular mass = 223.86
Percent by mass Fe = (55.86/223.86)*100 = 24.95%
Percent by mass Cr = 46.45%
Percent by mass O = 28.59%</span>
