A 4.40 g piece of solid CO2( dry ice) is allowed to vaporize(change to gas) in a ballon. The final volume of balloon is 1.00 L at 300L. What is the pressure of the gas?
At a certain temperature, a saturated solution contains 537 g of NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution.
the pressure is found to be 1atm. 3 g of gaseous substance B are then added to the 2g of A, and the pressure is now found to be 1.5 atm. Assuming ideal gas behavior. calculating the ratio of molecular weights, that is MwA/ MwB
