Enthalpy Calculation .Enthalpy change from eating gummy bears C 12H22011 (from gummy bear) + 1 202(g) 12CO2(9) + 11H2O() AH-5645 kJ/mol At your desk with your group: What is the enthalpy change for a 3.05 gram gummy bear?

Solution

Molar mass of C₁₁H₂₂O₁₁ is 342 g/mol

Let x be the enthalpy change for a 3.05 g gummy

342 g gives---------------------> 5645 KJ

3.05 g gives---------------------> x

cross multiply 342*X=5645*3.05

X= -50.3428 KJ
