6x/12x
6/12 × x/x
1/2 × 1
1/2
the answer is A
For this case we have the following quadratic equation:

Where:

We look for the solution using the following formula:

Substituting the values:

Thus, we have two roots:

Answer:

<h2>Hello!</h2>
The answer is:
The first measurement of volume is equal to 835.23 mL.
<h2>Why?</h2>
Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.
So, we Boyle's Law equation states that:

Where,

Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:

So, substituting the given information and calculating, we have:


Hence, the first measurement of volume is equal 835.23 mL.
Have a nice day!
