1 mL = L
so $155$ mL =$155\times10^{-3}$ L
Now, $1$ gallon = $3.785$ L , or $1$ L= $\frac1{3.785}$ gallons
so $155\times10^{-3}$ L= $155\times10^{-3}\times \frac{1}{3.785}=40.95\times 10^{-3}$ gallons
and this is for each day, so just divide by 1 (day) to get the ratw gallons/day
i.e. $40.95\times 10^{-3}$ gal/day

Answer: 1.5 moles O2
Explanation:
The number of moles of each reactant and product is the number in front to the molecule when the equation is balanced.
You know that 1 mole of O2 gives you 2 moles of H2O
So you can set up a proportion using that.
1 mole O2. X moles O2
-------------- = -------------------
2 moles H2O. 3 moles H2O
Then cross multiply
2x=3
X=3/2 Or 1.5
So you need 1.5 moles O2 to get 3 moles of H2O.

Answer:
2 moles of NO
Explanation:
Our reaction is:
4NH₃ + 5O₂ → 6H₂O + 4NO
4 moles of ammonia react to 5 moles of oxygen in order to produce 6 moles of water and 4 moles of NO
We need to determine the limiting reactant:
Ratio is 4:5, As 4 moles of ammonia react to 5 moles of oxygen and we have 4 moles, we definetely need 5 moles, but the problem is, we only have 2.5 moles of O₂. Oxygen is the limting reagent.
5 moles of O₂ produce 4 moles of NO, according to stoichiometry
2.5 moles of O₂ may produce (2.5 . 4) / 5 = 2 moles of NO
