PLS HELP ASAP I BEG HEH... The table shows the amount of radioactive element remaining in a sample over a period of time.
(photo of the table attached)

Part 1: What is the half-life of the element? Explain how you determined this.

Part 2: How long would it take 308 g of the sample to decay to 4.8125 grams? Show your work and explain your answer.

Yapo 13 fool coming at you for it

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.
