Substance Symbol Graham Crackers Marshmallow Mm Chocolate Pieces S'more SzMmOr3 Unit Mass 6.86 g 7.86 g 3.58 g ? g Package 454 g 283 g 43.0 g Or 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. Calculate the molecular mass of the S’more (S2MmOrz). 4. Write a chemical equation using the symbols given in the table.

Answer 1

1) The formula for S'more – S₂ Mm Org mass of a bag of mar. The mass of marshmallow in a bag - 2839 unit mass of marshmallow no of of marshmallow moncha n in -7.86 to y total mass unit mass a hea a bag- - 283 = 36 units 283 7. 86 Now, the formula of Smore - Sammor, F one Smore Contains One marshmallow so with 36 cinits of marshmallow 36 units of S'more can be made. 36 Smores are to be made Imore und I m Orz one s'more contains 2 graham cracker and 3 chocolate bars. s so 36 contain 2x36= 72 and Smore Or 3x36 - 108

Now, No of units of s and or in their respective bags are are – G. 18 No of a mass total abit mass = 454 6.86 67 No of Ora 43 - 12 3.58 For getting 72 units of s 2 bags are required 108 For getting 108 units of Or 108 - a bags regain s requer ed 12 molecular mass of Smore can be calculated by adding total mass of elements in one s'more molecule. Sq Mm Ora Molecular mass - 2x mass of s fix mass of mm. + 3x mass Ora - 32.32 %oit single state 4 Assuming S, mm Or are in equation chemical reaction will be The SMm Ora 25+ m + 30% -
