Acetylene (C2H2) reacts with oxygen (O2) to produce water and carbon dioxide (CO2). How many grams of carbon dioxide are produced when 12.5 grams of acetylene are reacted?

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

there are two significant figures.

i believe the answer is 5,000
