How many moles of aluminum are needed to produce 146 grams of aluminum oxide?

I beleive this should help you find ur answer The molecular mass of Aluminum Oxide is approximately 102 grams per mole. 105.9 g Al were burned in excess O2 to produce 200.0 g Al2O3

Explanation:

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
