Vedclass · Answer

(B) $1$. The osmotic pressure $\pi$ is given by the hydrostatic pressure formula: $\pi = h ho g$.$2$. Convert height to meters: $h = 80.0 	ext{ mm} = 0.08 	ext{ m}$.$3$. Calculate $\pi$: $\pi = 0.08 	ext{ m} 	imes 1000 	ext{ kg m}^{-3} 	imes 10 	ext{ m s}^{-2} = 800 	ext{ Pa} = 0.8 	ext{ kPa}$.$4$. Use the osmotic pressure formula: $\pi = CRT = (n/V)RT$, where $n = 	ext{mass}/M$.$5$. Substitute the values: $0.8 = (20 / M) / 1 	imes 8.3 	imes 300$.$6$. Solve for $M$: $M = (20 	imes 8.3 	imes 300) / 0.8 = 62250 	ext{ g mol}^{-1} = 62.25 	ext{ kg mol}^{-1}$.$7$. The nearest integer is $62$.
