Question

Plants breathe in carbon dioxide to make sugar through photosynthesis. How much sugar can they create if 200 grams of carbon dioxide are used? 6 CO2 + 6 H2O -> C6H12O6 + 6 O2 Question: How many molecules of sodium oxide will be created if 187 grams of oxygen reacts with excess sodium? 4 Na + O2 -> 2 Na2O Question: If you reacted 88.9 g of ammonia with excess oxygen, what mass of water would you expect to make? You will need to balance the equation first. NH3(g) + O2(g) -> NO(g) + H2O(g) Question: What mass of zinc oxide would be produced by the thermal decomposition of 375 grams of zinc carbonate? ZnCO3 -> ZnO + CO2

Step 1

Given: 6 CO2 + 6 H2O -> C6H12O6 + 6 O2 Molar mass of CO2 = 44.01 g/mol Molar mass of C6H12O6 (glucose) = 180.156 g/mol 200 g CO2 * (1 mol CO2 / 44.01 g CO2) * (1 mol C6H12O6 / 6 mol CO2) * (180.156 g C6H12O6 / 1 mol C6H12O6) = 136.5 g Show more…

00:01 Uploaded this problem, uploaded four questions, four stochiality questions in one problem.

00:11 Submission.

00:13 I'm going to do two.

00:14 I will do two.

00:18 I'm not going to do four stoichiometries in one problem.

00:21 Our first problem is about plants breathing carbon dioxide, and we're given the following chemical reaction.

00:33 Carbon dioxide and water produce glucose and o2.

00:44 And our question is, how many molecules, how much sugar can they create? how much? and i'm going to calculate that in grams if we have 200 grams of co2 used.

01:04 So this will be a mass mass calculation.

01:08 And we'll be starting with 200 grams of co2.

01:16 Co2 is 44 .01 grams per mole.

01:24 This is the molar mass and we're asked to go to grams of glucose and finally we'll use the molar mass of glucose which is about 180 i'm going to verify 180 what and i'm just looking up that molar mass 180 .156 grams and i'm just going to write g for glucose per mole of glucose because i'm out of room there and that will equal 200 times 180 .0 .0 .0.

02:22 156 divided by 44 .01 divided by 6 and that will equal 136 .5 grams.

02:44 Now this is a little strange because we were given 200 grams which is one of our givens was only given to one significant figure.

03:00 So we would only be able to report this to one significant figure...
