Answer:

Well first, you have to decide what a #"QUART"# is! In the UK this is #"2 pints"#, #1200# #mL# (#=# #1.200*L#). In the States, it is #0.946# #L#. https://en.wikipedia.org/wiki/Quart

Explanation:

In both US and Imperial systems a #"quart"# is short for a QUARTER of a GALLON. Of course, the US gallon and the Imperial gallon are different.

Given that #1# #US# #quart# #=# #0.946# #L# or #946# #mL#, #25.00# #mL# #=# #(25.00*cancel(mL))/(946*(cancel(mL)*"quart"^-1)# #=# #??# #"quarts"#.

It's questions like these that remind me how truly decadent the Imperial system of measurement is: pounds, ounces, feet, furlongs, chains, poles. Of course, we are going to be stuck with these units for some time. In the question above I was able to solve the problem dimensionally, i.e. I had the conversion #mL*"quart"^-1#, and when I did the calculation the extraneous units cancelled out.

Do not be persuaded that these conversions are easy. Anyone can make an error, and the 2 systems of measurements (actually 3 systems of measurement) are hard to interconvert.
