<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
All you have to do is a simple division "parts over the whole"
12.3 grams H/ 110 grams compound x 100= 11.2%

When balancing a chemical equation, a coefficient within a chemical equation can be adjusted to balance the chemical equation.
<h3>What is a Chemical equation?</h3>
This is defined as a written expression of a chemical reaction and contains the reactants and products which are involved.
It also has to be balanced which means that the number of atoms of elements on the reactants side has to be equal to that on the product side.
This is therefore the reason why only coefficients are adjusted to ensure the equation is balanced. Other parts such as the superscripts and subscripts shouldn't be adjusted in this scenario.
