In an experiment, 12.0dm3 of oxygen, measured under room conditions, is used to burn completely 0.10mol of propan-1-ol. what is the final volume of gas, measured under room conditions? a 7.20dm3 b 8.40dm3 c 16.8dm3 d 18.00dm3 ans is b. pls explain how

The correct answer is option D.

Explanation:

At room conditions ,temperature is taken as T =293.15 k

At room conditions, pressure is taken as P = 1 atm

Given the volume of oxygen gas = = 12.0 L

Using Ideal gas equation:

n = 0.4992033 moles of oxygen gas.

Initial number of moles of oxygen gas = 0.4992 mol

According to reaction, 2 moles of propanol reacts with 9 moles of oxygen.

Then 0.10 moles of propanol will react with:

Final moles of oxygen gas left after combustion reaction = n'

n'= 0.4992 mol - 0.45 mol = 0.0492 mol

So, the final volume of the oxygen gas measured will be given as:V'

V' = 1.18 L

Volume of the

According to reaction, 2 moles of propanol gives  with 6 moles of .

Then 0.10 moles of propanol will give :

Volume of the

According to reaction, 2 moles of propanol gives  with 8 moles of .

Then 0.10 moles of propanol will give :

Total volume of the gas measured =

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
