Example 1: To find the percent composition of red M&Ms in a bag of 200 M&Ms, if there are 26 red, you would use this formula. Mass of Sample x 100 = Percent Composition Total mass in the sample So, in the M&Ms problem: 26 red x 100 = 13% 200 total Example 2: Find the percent composition of copper (Cu) in CuBr2. Mass of Cu in the compound x 100 = Percent Composition Total Mass of CuBr2 Compound 63.546 grams x 100 = 28.4% 223.354 grams Percent Composition Practice Find the percent compositions of all of the elements in the following compounds: 1) CuBr2 Cu: ___________ Br: ___________  2) NaOH Na: ___________ O: ___________ H: ___________  3) (NH4)2S N: ___________ H: ___________ S: ___________  4) N2S2 N: ___________ S: ___________  5) KMnO4 K: ___________ Mn: ___________ O: ___________  6) HCl H: ___________ Cl: ___________  7) Mg(NO3)2 Mg: ___________ N: ___________ O: ___________  7) (NH4)3PO4 N: ___________ H: ___________ O: ___________ P: ___________  8) Al2(SO4)3 Al: ___________ S: ___________ O: ___________ Percent Composition Worksheet Answer Key Find the percent compositions of all of the elements in the following compounds: 1) CuBr2 Cu: 28.4% Br: 71.6%  2) NaOH Na: 57.5% O: 40.0% H: 2.5%  3) (NH4)2S N: 41.1% H: 11.8% S: 47.1%  4) N2S2 N: 30.4% S: 69.6%  5) KMnO4 K: 25% Mn: 35% O : 40%  6) HCl H: 3% Cl: 97%  7) Mg(NO3)2 Mg: 16% N: 19% O: 65%  8) (NH4)3PO4 N: 28% H: 8% O: 43% P: 21%  8) Al2(SO4)3 Al: 16% S: 28% O: 56%     46AB # 1 ; < = I } ~ ! ) * }   & ߻߻߫Ϣ~pepeh0WhBYmHsHjhBYUmHnHuh0WhBYH*mHsHh0WhBYmHsHhBYh45>*CJ$hBY5>*CJ$htL?htL?CJ htL?>*CJhtL?htL?>*CJhtL?htL?CJH*h/h/CJ h/>*CJ htL?CJhoDhtL?5>*CJ h/CJh/5>*CJ$'456AB    2 < = I J * + | } gd/$a$}     + , - . = > P Q $a$& ' ( ) ` a g h i j n    = > ? @ Ҹ֪~v~v~rncUjh'wUmHnHuh}D8h'wmHsHh'wh}D8h}D8h}D8H* h}D8h}D8h}D8mHsHjh}D8UmHnHuh}D8humHsHhujhuUmHnHuh0Wh0WH*jh0WUmHnHuhPbh0WhBYjhBYUmHnHuh0WhBYmHsHh0WhBYH*mHsH Q ` b c k l m n } ~ $a$gd0Wgd0W$a$     . / > ?
