When 1 g of urea (MW = 60) is diluted to 100 ml of water, what is the osmotic pressure of the solution (assume T = 300 K, R = 0.0821 L atm K-1 mol-1 ). What is the osmotic pressure of the same concentration of NaCl, assuming complete dissociation of the salt?

Which of the following would have less momentum than a 52 kg cheetah running at 10 m/s?

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
