Question

Approximate Molar Mass of Metal (g/mole) (Equation 3) Compare your molar mass to the following list of metals: aluminum, copper, zinc, tin, platinum, iron, nickel, silver, titanium, tungsten Unknown metal: Part B: Energy Content of Foods Mass of stopper assembly (pan, paperclip, and stopper) Mass of empty test tube + beaker 59.92 g 175.77. 185.60 g Mass test tube + 10mL water + beaker Mass of water Burning Foods: Type of Food Froot Loop Cheeto Puff Popcorn Marshmallow Mass Assembly + Food Mass Assembly + Burnt Food 159.92 60.89 59.88 60.79 159.70 59.87 60.42 60.665 Mass of food burned DATA SHEET Initial Temp water 121.4 | 24.43 Temperature Change, AT("C) 22.59 23.7 22.5 101 40.67 37.5 Total heat produced by food burned (egn. 4) Heat produced per gram of food burned (egn. 5) Total heat produced by food burned 1 (AT) (mass of water) + (heat capacity of test tube)(AT) Equation 4 - NOTE: the heat capacity of your test tube is 62 Heat produced per gram of food burned Total heat produced mass of food burned Equation 5 134 Page

Answer 1

Exploration Typex of food (frent loop) Mass of food burned = sqrty 59.99.59 70 Temporcature change 0.229. = 94.43-2114 = 3.63°c. Total heat produced by food buangd - 3.03 x 9.83 1 & 62 x 3.03. = .217.64 Cat. Mass of water = 185.50-175. = 9.83.9. Heat produced per grans of food binned at = 217.69 0-92 - 889.295 similanly we can do the same calculations for other fools.
