Number of Half Lives Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Half Lives = Total Time/Half Life
n = t_total/t_1/2
This formula uses 3 Variables

Variables Used

Number of Half Lives - Number of Half Lives is defined as the total time needed for the disintegration of the substance which is divided by the half-life of the substance.
Total Time - (Measured in Second) - Total Time is defined as the time required to disintegrate the radioactive substance to a certain value.
Half Life - (Measured in Second) - Half Life is defined as the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay.

STEP 1: Convert Input(s) to Base Unit

Total Time: 480000 Second --> 480000 Second No Conversion Required
Half Life: 0.0034 Year --> 107293.6368 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n = t_total/t_1/2 --> 480000/107293.6368

Evaluating ... ...

n = 4.47370425978514

STEP 3: Convert Result to Output's Unit

4.47370425978514 --> No Conversion Required

FINAL ANSWER

4.47370425978514 ≈ 4.473704 <-- Number of Half Lives

(Calculation completed in 00.006 seconds)
