In a well-fed adult camel, this can weigh as much as thirty five kilograms. The metabolism of this fat enables the camel to lose up to hundred litres of water without ill effects. For the reason of this exercise let us suppose that 1/2 of the weight of the hump (17.5 Kg) may be attributed to a saturated fatty acid, single, palmitic acid (16:0) that has molecular weight = 25 the compute the water volume that is released upon its total metabolism to carbon dioxide and H2O, taking into account any oxidative phosphorylation that might occur.
If 86.0 mL of .150 M HCL is needed to neutralize all the NH3 from a 2.25-g sample of organic material, calculate the mass percentage of nitrogen in the sample.
