Asolution of heparin sodium, an anticoagulant for blood, contains 1.8 g of heparin sodium dissolved to make a final volume of 15 ml of solution. what is the mass/volume percent concentration of this solution?

12% mass/volume

Explanation:

The mass volume percent concentration (%m/v) expresses how much grams of solute are dissolved in 100 ml of solution, and it can be calculated with the following expression:

% m/v = g solute/100 ml solution

We have 1.8 g solute (heparin sodium) in 15 ml of solution, so we can obtain  %m/v as follows:

%m/v= x 100 ml = 12 % m/v

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
