Answer:
The answer to your question is:
Explanation:
Data
moles H=?
moles of N = 0.0969
moles of NH₃=?
N₂ (g) + 3 H₂ (g) ⇒ 2NH₃ (g)
Process
1.- Set a rule of three to calculate the moles of hydrogen
1 mol of nitrogen ------------- 3 moles of hydrogen
0.0969 moles of N ---------- x
x = (0.0969 x 3) / 1
x = 0.2907 moles of hydrogen
2.- Set a rule of three to calculate the moles of ammonia
1 mol of nitrogen -------------- 2 moles of ammonia
0.0969 mol of N -------------- x
x = (0.0969 x 2) / 1
x = 0.1938 moles of ammonia

Answer:
Constant volcanic eruption
Explanation:
So in one hour half the amount remains (that's what half life means). In two hours 1/4 (or half of half) would remain and in three hours 1/8 would remain.
So the answer is 1/8
The mole fraction of methanol in the mixture is 0.444
We'll begin by calculating the number of mole of water.
- Molar mass of water = 18 g/mol
Mole = mass / molar mass
Mole of water = 45 / 18
Mole of water = 2.5 moles
Finally, we shall determine the mole fraction of methanol.
- Mole of water = 2.5 moles
- Mole of methanol = 2 moles
- Total mole = 2 + 2.5 = 4.5 moles
Mole fraction of methanol =?
Mole fraction = mole / total mole
Mole fraction of methanol = 2 / 4.5
Mole fraction of methanol = 0.444
Thus, the mole fraction of methanol is 0.444
