If you have 8.943 l of carbon monoxide gas at satp, how many moles would it contain?

Consider the following intermediate chemical equations. ch4(g) + 2o2(g) → co2(g) + 2h2o(g) 2h2o(g) → 2h2o(1) which overall chemical equation is obtained by combining these intermediate equations? ch4(g)+2o2(g) → co2(g) + 2h2o(1) ch4(g) +202(g) → co2(g) + 2h2o(g) ch4(g) + 2o2(g) → co2(g) + 4h2o(g) + 2h2o(1) ch4(g) + 2o2(g) → co2(g) + 6h2o(g)
