When trying to measure the 0.250 molar solution (of which is in water and sodium phosphate solution) in 500 mL, there are very specific steps in which you need to follow. Pouring the correct amount of the solution in the beakers is important, as to make sure that the solution is not over concentrated, or under concentrated. if you were to use a flask that had a different volume amount, and filled that flask up to (for example one flask with five hundred milliliters.) the full amount,the solution would be less concentrated. The less of a liquid there is, the more the substance put in the liquid would be concentrated. When balances and scales are used, this is just to measure if for example two different beakers are used, each with a different
