What is the percent CdSO4 by mass in a 1.0 molal aqueous CdSO4 solution?
A solution was prepared by dissolving 1 g of NaHCO3 in 100mL of water. Explain how much anhydrous sodium carbonate, NaCO3 must be added to this solution thus that the pH of the resultant mixture is 10.33
If 2 x 10-4 moles of S2O8 ^2- in 50 mL of solution is consumed in 188 seconds, what is the rate of consumption of S2O8^2-?
A football is inflated to a pressure of 1.00 x 10^3 torr in a room at 25 degrees C. If the game is played at 10 degrees C, what will the pressure in the ball be, neglecting any volume change in the ball and assuming that it doesn't leak?
