Find the equation for the work of a reversible, isothermal compression of 1 mol of gas in a piston/ cylinder assembly if the molar volume of the gas is given
Calculate the molarity of a solution made by dissolving 0.150 mol Na2SO4 in enough water to form exactly 760 mL of solution.
What is the freezing point (°C) of a solution prepared by dissolving 11.3 g ofCa(NO3)2 (formula weight= 164 g/mol) in 115 g of water? Assume that i=3.00 for Ca(NO3)2 and the molal freezing point depression constant for water is1.86°C/m.
The pressure of a gas is 817 torr at 55°C. The quantity of the gas is fixed and the volume remains constant as the pressure is adjusted to 102 torr. What is the resulting temperature of the gas?
