Question

If there are 50 grams of a radioactive element how much will be present after 1 half life,2,half life, and 3 half life

Answer 1

6.25g

a half life will take away half of the element so you wouldjut divide by 2 three times

Step-by-step explanation:

Answer 2

1HL- 25g, 2HL- 12.5g, 3HL- 6.25g

Step-by-step explanation:

When trying to calculate Half Lives (HL) you want to make sure that you divide by 2 every time as a half life cuts the amount in half so 50/2=25(1HL) 25/2=12.5(2HL) 12.5/2=6.25(3HL) and of course dont forget the unit which is grams
