Answer 1

Answer:

А с Mass of Mgo = 1:0216g. Initial demperature = 19.98 Final Temperature = 22.307c :: 91 = Tt- Ti = 22.307-19. = 2.407 capacity of tal = 4.1848/9.0 (near to water). Heat of Santion = m. c. 4T [g. Jgde xo] -1.0216 X 4.184 x 2.407 = 10:29 7. Heat capacity of Calorimeter - Cent. Leat = - (Q hot + 9 (old) = - 10.29 2. Mol of Man - mass 1.0216 atomic mass - 40 molar mass = 0.0255 mol - 10.29 0.1255 3/mol = 402.89 g/mol => Phot B.
