Three major resonance structures are possible for the following cation, which is the sigma complex of meta-addition of bromine in an electrophilic aromatic substitution. Two are given below, but are incomplete. Complete the given structures by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges.

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.
