Pls help, I dont get it :/

thanks, I only need the answers to the LAST PAGE ( Step9)

The unit mass are :

Gc = 7.85g

Mm= 7.34g

Ch= 3.36g

S'more = 33.14g

S'more Stoichiometry Adapted from "S'more Stoichiometry" by Carolo Honry Definitions: 'Stoichio' means element and 'metry' San Antonio, Txcess of measuring. The mass and quantity relationships among reactants and products in a reaction are found using the process of stoichiometry. Problem: 1) If you are given one bag of large marshmallows, what is the maximum number of S'mores that can be made 2) How many boxes of graham crackers and how many chocolate bars are needed to make this many S'mores? 3) if you had 1 bag of marshallows, 1 box of graham crackers and 2 chocolate bars. what would get used up first and what would you have left over? Solutions: 19 Step: Find the unit mass using the following symbols: (Hint: since you cannot weigh the ingredients, you will have to find the information on the back of the package) Substance Symbol Unit Mass Graham Cracker Gc Marshmallow Chocolate Pieces Ch S'more GcMmcha Calculate the unit mass of the S'more (GCxMmChabelow; Mm 2013 Step: Balonce the equation: What does the equation tell us? What do the coefficients representa The balanced equation coefficients represents the ratio between the and the that go together/are created. 34 Step: Using the above chemical equation, moke some S'mores and put them on a baking sheet. Preheat your oven to 350 and place S'mores into the preheated oven for approximately 7 minutes or unit the chocolate has melted (You may want to keep an eye on them to ensure that they don't burl--a chemical reaction :). Once done, remove S'mores from the oven and let cool for a few minutes before eating-Enjoy! While you are eating the S'mores, complete the following calculations: 4th step: Calculating the number of units/items given: Determine the number of unit marshmallows that are available in the bag. If there are 454 g marshmallows in one bog, how many marshmallows do you have? 5 Step: Finding the units of other substances in the reaction: Now, determine how many units of graham crackers and chocolate segments are needed to use up all of the marshmallows. Graham Crackers Chocolate Segments 6 Step: Convert your number of grohom. nd chocolate ents into mass (gram) values: When you go to the store, you cannot quickey defemine the exact number of graham crackers or chocolate segments there are in a box cr bar. The mass is easy to read, however. Using mass values: you can quickey determine how much you need to buy. Graham Crockers Chocolate Segments 7 Step: Finally-convert the masses into your needed units. In this case, if a box of graham crackers has a mass of 408 g, how many boxes do you need? Also, if one chocolate bar has a mass of 100 g, how many bars do I need? gth step: Limiting Reagent If you have 1 bag of Mm. 2 boxes of Ge and 3 Bars of Ch, what is the maximum number of s'mores you could make Hint: Determine the number of s'mores you could make from each of the ingredients separately, and then evaluate your answers 7 Step: Finally-convert the masses into your needed units. In this case, if a box of graham crackers has a mass of 408 g, how many boxes do you need? Also, if one chocolate bar has a mass of 100 g, how many bars do I need? gth step: Limiting Reagent If you have 1 bag of Mm. 2 boxes of Ge and 3 Bars of Ch, what is the maximum number of s'mores you could make Hint: Determine the number of s'mores you could make from each of the ingredients separately, and then evaluate your answers Step 9: How many units of your excess reagents would you have left over Find # Mm we have: Find # Mm we need to make s'mores (GcMmCha): Subtract: (have-need-excess) Find # Gc we have: Find # Gc we need to make s'mores (GC MmChal: Subtract: (have-need-excess) Find # Ch we have Find #ch we need to make s'mores (GcMmchel Subtract have - neede excess)
