0.069 mL 0.014 ml 14 mL 69 mL None of these

2. Van't Hoff's factor, i is incoporated into some equations due to
a constant value that adjust for the pressure in the lab some electrolytes break up into ions a correction factor that makes data match up with hypothesis Van't Hoff factor I is a constant that corrects all osmotic equations none of the above
