Asample of a compound contains 30.0 g c and 5.05 g h. its molar mass is 78.12 g/mol. what is the compound’s molecular formula? ch c2h2 c6h6 c6h

The correct answer would be the third option. C6H6 most likely is the sample of compound since its molar mass sums up to 78.12 grams per mole as compared to other choices. CH has only a molar mass of 13.02 grams per mole, C2H2 has a molar mass of 26.04 and C6H has a molar mass of 73.07 grams per mole.

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.
