How many liters of o2(g) measured at 22 degree and 763 Torr are consumed in the complete combustion of 2.55 L of dimethyl ether measured at 25 degree celsius and 748 Torr.

• Chemistry -

C2H6O + 3O2 ==> 2CO2 + 3H2O

Use PV = nRT and conditions listed to calculate n = number mols of the ether.

Use the coefficients in the balanced equation to convert mols dimethyl ether to mols O2.

Now use PV = nRT, substitute the conditions for O2 and solve for V in liters.
