Calculate the partial pressure of helium gas for a volume of 1.0 ✕ 10-6 m3 of 210Rn gas after 38 hours. The radon gas was originally placed in an evacuated container at 1 atm, and the temperature remains constant at 0°C. (t1/2 = 14.6 h for 210Rn.) What is the partial pressure of the radon gas after this time?

I need helppp with my AP chem lab
Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl. Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...
