Task 2: Can someone explain to me how to solve this problem? Or, for N2 under normal conditions, do I need to use the formula pV=nRT, or do I need to deduce n or m in another way? Thanks in advance 🙂

Loading...Unfortunately, I am not sure what its value is. My boyfriend and I were very unsure…
Can someone show me a reaction equation for fat hydrogenation? Oleic acid is supposed to be used as the starting material. But I don't know the reaction partner.
Good evening 😀 I wanted to ask if I calculated it correctly 🙂
Doesn't have to look good, just keep weight
Hellooo, I'm currently losing my mind over chemistry. It would be great if someone could help; I don't understand anything.
Right, over pV=nRT you can calculate the amount of material and from it the mass directly. I also suspect that standard conditions (20/25 °C) are accepted. Otherwise, it doesn’t make sense.
Do not forget that O2 can also be contained in the molecule in CO2 and H20. So…
I would have done it over the weight. First, determine the weight of H, C, N (i.e.: m(H2O*M(H2)/M(H2O))) if a difference to the weighing is obtained, O must still be present. Then I would have converted into quantities of material and set up the sum formula from the ratios.
If you want to compare solutions.
Solutions like to compare but my solutions are wrong again and I still don’t understand why, how should I send you my solutions?
Did you consider that N2 has M=28 g/mol?
for N2 I have first (pV)/(RT) calculated with (101325*0,000244)/(R*298,15) and then have the value * the molar mass of N therefore 14 but of course you have to be right 28 but must really sleep I try tomorrow morning again at the university you have time to answer tomorrow? Thank you very much
