if a 10cm cube pipette were not available, which one of the following would be the best way of measuring a 10cm cube portion of a solution?

a. weigh 10 times the mass of 1cm cube of the solution.
b. weigh 10g of the solution.

I think this is a trick question. There seems to be no difference in the two answers; however, a is the correct answer. If you know the mass of 1 cc then 10x that will be the mass of 10 cc. But the mass of 1 cc of the solution, due to the temperature and density differences, may not be 1 g and 10 g may not be 10 cc. I think the unknown density of the solution is the trick part.

but if the solution is pure water, then the two answers should be both correct?
