Blood,sweat,and tears are about 0.15 M in sodium chloride.Estimate the osmotic pressure of these solutions at 37 $\circ$ C.The gas constant is 0.0821 L.atm.mol^-1.K^-1.

Question

Quizplus · Accepted Answer

The osmotic pressure (π) can be calculated using the formula π = iMRT, where i is the van't Hoff factor (for NaCl, i = 2), M is the molarity (0.15 M), R is the gas constant (0.0821 L.atm.mol^-1.K^-1), and T is the temperature in Kelvin (37°C = 310 K). Substituting these values gives π = 2 * 0.15 * 0.0821 * 310 ≈ 7.6 atm.
