α-Linolenic acid ((9Z,12Z,15Z)-octadeca-9,12,15-trie noic acid; ALA)) is a poly-unsaturated, w-3 fatty acid with 18 carbons found in many food sources. Since humans cannot synthesize fats with double bonds past carbon #9, it is "essential" and must be obtained from the diet. If a serving of salmon contains 500.0 mg of ALA and all of it is completely oxidized via β-oxidation and the TCA, how many grams of water at room temperature can be brought to a boil using that energy? (Specific heat of water: 4.184 J/mol; heat of vaporization of water: 40.65 kJ/mol; molar mass of ATP: 507.2 g/mol; DG° of ATP hydrolysis = -30.3 kJ/mol)

Ci think not

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Of course: ) what’s your name ?

Yeah, but what are you trying to ask?
