We have air (21% o2 and 79% n2) at 23 bar and 30 c. 4. what is the ideal molar volume (m^3/kmol)? a. b. what is the z factor? what is the real molar volume?

58750.08068 is the answer i think

that tool would be a compass

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
