What is the concentration, in percent (v/v) of a solution containing 50mL of diethyl ether (C4 H10 O) in a 2.5L of solution?
v/v = 50 mL / 2500 mL x 100 = 2.0% v/v
Wouldnt it be 50mL/2550mL x 100 ??
No, the problem says 2.5 L OF SOLUTION which is 2,500 mL OF SOLUTION.

Well, that's quite a mouthful! Speaking of mouths, did you know that diethyl ether is sometimes used as an anesthetic in dentistry? So if you ever find yourself at the dentist, just think of this little fact to distract yourself from the big drill! But to answer your question, let's do some math here.
The volume of the diethyl ether is 50 mL and the total volume of the solution is 2.5 L. To find the concentration in percent (v/v), we need to divide the volume of the diethyl ether by the total volume of the solution and multiply by 100.
So, (50 mL / 2500 mL) x 100 = 2% (v/v)
Voilà! The concentration of diethyl ether in the solution is 2% (v/v).
To find the concentration of a solution, we need to know the amount of solute (in this case, diethyl ether) and the total volume of the solution. The concentration is usually expressed as a percentage by volume (v/v), which represents the volume of solute in 100 mL of the solution.
In this case, we have 50 mL of diethyl ether as the solute and a total solution volume of 2.5 L. We need to convert the solution volume from liters to milliliters to match the unit of the solute.
To calculate the concentration, we can use the formula:
Concentration (v/v) = (Volume of solute / Volume of solution) * 100
First, let's convert the solution volume from liters to milliliters:
2.5 L * 1000 mL/L = 2500 mL
Now we can substitute these values into the formula:
Concentration (v/v) = (50 mL / 2500 mL) * 100
Simplifying the equation:
Concentration (v/v) = 0.02 * 100
The concentration of the solution containing 50 mL of diethyl ether in a 2.5 L solution is 2% (v/v).
