Treatment of the following stereoisomer of 1-bromo-1,2-diphenylpropane with sodium ethoxide in ethanol gives a single stereoisomer of 1,2-diphenylpropene. draw the e2 elimination product of the reaction. take into account that the starting stereochemistry affects the resulting double bond stereochemistry. consider e/z stereochemistry of alkenes. do not show stereochemistry in other cases. you do not have to explicitly draw h atoms. in cases where there is more than one answer, just draw one.

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.

the awnser is group 12

i dont know the answe
