9.294 g of a non-volatile solute is dissolved in 305.0 g of water. The solute does not react with water nor dissociate in solution. Assume that the resulting solution displays ideal Raoult's law behaviour. At 60°C the vapour pressure of the solution is 148.07 torr. The vapour pressure of pure water at 60°C is 149.40 torr. Calculate the molar mass of the solute (g/mol). 61.1 g/mol You are correct. Your receipt no. is 162-1722 ? Previous Tries Now suppose, instead, that 9.294 g of a volatile solute is dissolved in 305.0 g of water. This solute also does not react with water nor dissociate in solution. The pure solute displays, at 60°C, a vapour pressure of 14.94 torr. Again, assume an ideal solution. If, at 60°C the vapour pressure of this solution is also 148.07 torr. Calculate the molar mass of this volatile solute. Note that the calculation is greatly simplified if you recognize that: \solute = 1- Xwater.

At high altitudes, mountain climbers are unable to absorb a sufficient amount of O2 into their bloodstreams to maintain a high activity level. At a pressure of 1.00 bar, blood is typically 95.0% saturated with O2, but near 0 feet where the pressure is 0.660 bar, the corresponding degree of saturation is 60.0%. Air contains 20.99% O2 by volume. Assume that the density of blood is 998 kg m -3 Part A Assuming that the Henry's law constant for blood is the same as for water (4.95 x 104 bar), calculate the amount of O₂ dissolved in 1.00 L of blood for pressure of 1.00 bar.
