This reaction involves an intramolecular aldol reaction followed by a retro aldol-like reaction. The steps involved are as follows: 1. Deprotonation to form enolate ion 1; 2. Cyclization via an intramolecular aldol reaction to form tetrahedral intermediate 2; 3. Collapse of the tetrahedral intermediate and bond cleavage to form enolate ion 3; 4. Protonation to form the final product. Write out the reaction on a separate sheet of paper, and then draw the structure of enolate ion 3

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

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
