**Finding the Half-Life Question Science Mathematics**

Math radioactive isotope half life. fraction remaining, f = 0.5^(t/h) , where h is the half-life 0.08 = 0.5^(200/h) (200/h)*ln 0.5 = ln 0.08 h = 200*ln 0.5 / ln 0.08 = 54.89, â‰ˆ 55 days <-----How many atoms fraction remain after 30 minutes if 1 half life is 20 minutes. The key to solving exponential growth or decay problems (which includes half-life problems) is to understand the terms in the... The half-life of a radioactive element is a fundamental property of the element. It is measured by experiment, just like its mass or its hardness can be measured. One way of doing this would be to take a sample of the element and measure the n...

To use the half life calculation, you need to know the number of half lives that pass. Divide the amount of time that has passed by the half life of the substance to find the number of half lives. For example, if your substance has a half life of 1 month and the total time equals 12 months, divide 12 by 1 to find that 12 half lives have passed. how to find if your company is gsa schedule 29/12/2017Â Â· i'm trying to find the half life of a substance. i've seen some equations online, but when i carry them out the answer i get is different than the answer i get from using sites that calculate it for you. for example, how would i find the half life of a substance where the initial quantity is 12, the remaining quantity is 3, and the time that.

## How To Find The Half Life Math

### More generally, if we want to calculate the time it takes for a radioactive substance to decay to half of its initial quantity we find the following:

- 12/04/2015Â Â· so then i thought if i lose 50% in 30 years. then in 20 years, which is 66% the amount of time needed for another half life to pass, then i should lose 66% of the 50% which is only 33%. so in 50 years i lose 33% of the 50% lost in the first 30 years. but then i â€¦
- However, to determine the decay at different times after measuring the activity, find the natural log of the time elapsed divided by the isotope's half-life. Then multiply that number by the calculated rate of decay taken at the time referenced by the equation.
- Calculating and Using Half-Life The half-life of a substance is the time it takes for the substance to lose half of its pharmacological, physiological, or radiological characteristic.
- A more intuitive characteristic of exponential decay for many people is the time required for the decaying quantity to fall to one half of its initial value. This time is called the half-life , â€¦
