chemistry
When methanol undergoes complete combustion, the products are carbon dioxide and water. 2CH3OH (l) + 3O2(g) --> 2CO2(g) + 4H2O (g). How much water ( in grams) can you maximally produce if you burn 50g of methanol? In real experiment, you isolate 10 mL of water (d=0.98 g/cm3...

chemistry question
You have the balanced equation. Convert 346 g CO2 to mols. mol = g/molar mass Using the coefficients in the balanced equation, convert mols CO2 to mols propane. Now convert mols propane to grams. g = mols x molar mass. Post your work if you get stuck.
