539.28kJ x (1mol/ 6kJ) x (28g / mol N2) x (1mL/11g) x (1L/1000mL) = ? Please only answer if you know it! I already this posted this question a few times to have it commented on by scam users so I will now be emailing the moderators to ban any inapplicable answers or self promotions. This question is super important to me as its the final piece of my project due tomorrow.

if what you need is the final answer

the final answer is = 0.228 and I think the unit is Liter(L).

Explanation:

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
