How many moles of oxygen are produce dif 11.0 mol of al are produced

8.25 moles

Explanation:

Given parameters:

Number of moles of Al produced = 11 moles

Unknown:

Number of moles of oxygen produced = ?

Solution:

To solve this problem, we need to understand the problem.

The decomposition of an aluminium oxide must has produced oxygen and aluminium,

              2Al₂O₃   →  4Al  + 3O₂

now since the known is the oxygen gas; we can find the unknown aluminium:

                3 mole of O₂ was produced with 4 mole of Al

               x mole of O₂ will be produced with 11 moles of Al

 x  =  = 8.25 moles

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.

there is none because earth is stationary and flat.
