Need Help for Half Life Problems using Logs
Hi, I need help with solving half life problems using natural log. Or normal log. I learned this before, but totally forgot how to do it right now before the Final Exam, please help. (Doh)
The equation that I got was:
N = No (1/2) ^ t
N is final amount, No is the initial ammount and t is time.
I was given the data:
Time (min) 10 20 30 40
Amount (g) .83 .68 .56 .46
and I need to find the regression equation, write an equation in terms of base e, and use the equation to predict the half life.
How do I do this? I have no clue... (Doh)
