a. .250 moles
Explanation:
Hello!
In this case, since we can see how the hydrogen is given off as a product of the reaction and we can model its behavior via the ideal gas equation, it is possible for us to use such equation for the determination of the collected moles:
Next, since the STP conditions account for a pressure of 1 atm and a temperature of 273 K, the moles turn out to be:
Thus the answer is a. .250 moles
