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

a electronegativity decreases beacuse the size of nucleus is bigger.
