Now the next question is, what's the mass of hydrogen Which is the limiting reactant? Sacramento CA 95833, Everything about California water that matters, Western States Water Agencies and Districts. You cannot convert a volume of gas into a mass by an easy conversion factor, you have to use the ideal gas law: Express answer with the appropriate units. Step by step calculations used to figure the water 10th - 11th grade . Just by coincidence rounding off early here doesn't change the final answer. It should be fairly obvious that you could have plugged in the mole fraction right away in this particular example because only one type of atom was present on both sides of the equation. Since the question asked for the number of grams of water that will be produced, we need to convert this molar value into mass. California has a history of multi-year droughts and periodic years of abundant rain. Food Facts: How Much Water Does It Take to Produce ? This is assuming all the hydrogen will be converted into water.

However, it's good to know the procedure for when you come across more complicated problems to solve. We know that there are 7 mol of water formed, so we use the molecular weight of water that we just calculated to find the mass of water formed: mH2O = nH2O * MWH2O = 7 mol *18.02 g/mol = 126.14 g. As an added challenge, can you use the same method to find the mass of hydrogen that must be reacted with 3.5 mol of oxygen to form 7 mol of water? The ratio of a reactant / product to a different one - compared by the number of particles. She has acted as a copywriter and screenplay consultant for Advent Film Group and as a promotional writer for Cinnamom Bakery.
