A hydrocarbon (Ma=224.253 g/mol) found to contain 64.27% carbon and 7.19% hydrogen by mass, the remainder was oxygen. Combustion analysis of a 18.4 g sample of this compound produced CO2(g) and H2O(g), that were collected in a container at 27o C. The final pressure of the container was measured as 1.50 atm. What is the partial pressure of CO2(g) and H2O(g)?

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
