The fat stored in the hump of a camel is a source of energy and water.
Calculate the mass of water produced when 1 kg of fat is metabolized. Assume the fat consists entirely of the animal fat, tristearin (C57H110O6), and that tristearin reacts with oxygen to form only carbon dioxide and water.
The strings:
S7P1A15 (containership-mass).
S7P6A66 (grouping/interaction- chemical)
The math:
Pj Problem of Interest is of type containership (mass).
Balanced equation of tristearin and oxygen reaction:
2C57H110O6 + 163O2 -------> 114CO2 + 110H2O
Molar mass of C57H110O6 = 57x12 + 1x110 + 16x6 = 684 + 110 + 96 = 890 g
So, 1 kg of C57H110O6 is the weight of 1000/890 = 1.124 moles of C57H110O6.
2 moles of C57H110O6 produced 110 moles of water
So, 1.124 moles will produce (1.124 x 110)/2 = 61.82 moles of water
So, mass of water produced = 61.82 x 18 = 1112.76 g = 1.1 kg.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
