Asked by jessie

write a balanced reaction for 50.92 grams of carbon disulfide,including molar masses. then calculate the moles of carbon disulfide and oxygen. now find the mass of oxygen consumed in the reastion.

HELP!!!

CS2 + 3O2 ==> CO2 + 2SO2

Your question isn't completely clear as to the reaction. I assume the above is it. Now you write in what you know and tell us what you don't understand.

1 mole of CS2 = 12.011 + 32.066x2 = 76.143 g/mol

(50.92 g) / (76.143 g/mol) = 0.66874 moles CS2

Based on the chemical equation DrBob gave you for the combustion of CS2,
(0.66874 mol CS2)(3 mol O2 / 1 mol CS2) = ___moles O2

To get the mass (grams) of O2 consumed in the reaction, multiply the moles of O2 by the molar mass of O2.
