Human fat has a density of 0.87 g/ml. What is the average volume of fat removed in milliliters) 3.535 5 pts)

Answer 1

i) Sn​​​+4 + 2e-  = Sn​​​​​2+

This this is reduction as oxidation state is decreasing from +4 to +2.

ii) O​​​​​​2​​​​​° + 4e- = 2O 2-

Oxidation oxidation state decreases from 0 to +2 so it is reduction.

Part 2

Fat in lbs = 2.2 × Fat in Kg

6.5 = 2.2 × Fat in Kg

Fat in kg = 6.5/2.2 = 2.95 Kg

Volume (ml) × Density (g/ml ) = Mass (gm)

Volume = 2950 gm/ 0.87 gm

= 3390.8 ml
