A student is ready to determine the density of their 10% solution. He has run out of clean beakers and decides to reuse the beaker that contained the stock(concentrated) solution. The student notices that there is a little stock solution left in the beaker. However, he decides to go ahead and use the dirty beaker. How will his decision affect the outcome of his results? a. The density will be less, since the density of the solution is now less than 10%.
b. The density will be greater, since the density of the solution is now greater than 10%.
c. This decision will not affect the density, since the majority of the solution is the 10% solution.
d. The density will be the same, since he will estimate how much water needs to be added to the beaker to compensate for the leftover stock solution.
