2C2H2 + 5O2 --> 4CO2 + 2H20

How many grams of CO2 is produced when 2.50 x 10^4gC2H2 burns completely

2.50 x 10^4gC2H2 * 44.009gCO2/26.038gC2H2 = 4.23x10^4gCO2?

or am i wrong

• Chemistry -

you erred. You did not use the balanced equation coefficents.

2.50 x 10^4gC2H2 * 4*44.009gCO2/2*26.038gC2H2 = you do it.
