Intravenous infusions are usually made with the help of the gravitational force. Assuming that the density of the fluid being administered is 1,080 kg/m^3, at what height should the IV bag be placed above the entry point so that the fluid just enters the vein if the blood pressure in the vein is 2.36 x 10^3Pa above atmospheric pressure? Assume that the IV bag is collapsible. (Hint: Atmospheric pressure is applicable in the entire situation) Answer to 3 sig figs.

A fluid has a mass density of 1,169 kg/m?. How many cubic meters of this fluíd weighs 100 pounds on Earth? (1 kg weighs 2.2 pounds on Earth). Answer to 3 sig figs

I somewhat understand what formula to use to get the answer; but i having problem of trying to the argument in logical way;
