The pressure of a gas contained in a cylinder with a movable piston is 2.62 torr. The area of the piston is 0.7 sq. meter.

Calculate the force that is exerted on the piston.

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

Define dew point. i am writing this part to be able to ask the question

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
