My question is the following: For each fo the following unbalanced equations, calculate the mass of each product that cold be produced by complete reaction of 1.55 g of the reactant indicated in the bold face. Then one of the questions is like: CS2+ O2->CO2+SO2. The boldface is the O2. My main question is what do they mean by the 'calculate the mass of each product'? Do they mean to find the grams of each, or the moles of each? Could you show me an example of how you would do it? Thanks a bunch!
