A mixture of toluene and water boils at 90 C, calculate the vapor pressure of toluene at this temperature. Assume the atmospheric pressure to be 760 mmHg. And secondly calculate the molar mass of toluene.
Could you hardboil and egg on the moon? Options: *Yes, because water boils spontaneously on the moon. *No, because water boils at such a high temperature that it would cause the egg to disintegrate before it became hard-boiled.
A sample of hydrogen gas (H2) is produced in a laboratory by displacement of water. A 645 mL sample of hydrogen is collected at 25 degrees Celsius and a total pressure of 758 torr. Collecting gas by water displacement causes the
An ideal solution made up of benzene C6H6 and toluene C6H5CH3 has mole fraction of benzene as 0.025,0.5,0.75,1.0 at various concentration. calculate the molar fraction of toluene Calculate the total vapour pressure of the solution
Calculate the volume of solution that has a vapour pressure of 31.27 mbar and contains 84.3g of sucrose, at a temperature of 25.0C. The vapour pressure of pure water at 25.0C is 31.7mbar, the density of water is 1.00g/mL, and
I don't understand how to even start this problem: A mixture of H2(g), O2(g), and 2 mL of H2O is present in a 0.5 L rigid container at 25 degrees Celsius. The number of moles of H2 and the number of moles of O2 are equal. The
