Oxidation of zinc produced a #47.5*mL# volume of dihydrogen at #1*atm# and #273.15*K#. What is the molar quantity of zinc that reacted?
I will do this for
We investigate the redox response...
To find the molar quantity, we apply the outdated Ideal Gas Equation.

Using the ideal gas law , where is pressure, is volume, is the number of moles, is the gas constant, and is temperature:
We rearrange the formula to solve for moles ():
Given:
- (gas constant)
Now, plug in the values:
Therefore, approximately 0.00212 moles of zinc reacted.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
