The empirical formula of a compound is CH. At 200ºC, 0.145 g of this compound occupies 97.2 mL at a pressure of 0.74 atm. What is the molecular formula of the compound?
A certain hydrate has the formula MgSO 4 x H 2 O. A quantity of 54.2 g of the compound is heated in an oven to drive off the water. If the steam generated exerts a pressure of 24.8 atm in a 2.00-L container at 120ºC, calculate x .

Interstellar space contains mostly hydrogen atoms at a concentration of about 1 atom/cm 3 . a) calculate the pressure of the H atoms in interstellar space b) calculate the volume (in L) that contains 1.0 g of H atoms in interstellar space (the temperature is 3 K)
A barometer having a cross-sectional area of 1.00 cm 2 at sea level measures a pressure of 76.0 cm of mercury. The pressure exerted by this column of mercury is equal to the pressure exerted by all the air on 1 cm 3 of Earth’s surface. Given that the density of mercury is 13.6 g/mL and the average radius of Earth is

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
