## Number of Half Lives Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Half Lives = Total Time/Half Life
n = ttotal/t1/2
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 = ttotal/t1/2 --> 480000/107293.6368
Evaluating ... ...
n = 4.47370425978514
STEP 3: Convert Result to Output's Unit
4.47370425978514 --> No Conversion Required
4.47370425978514 4.473704 <-- Number of Half Lives

Packing Fraction (In Isotopic mass)
​ Go Packing Fraction in Isotopic mass = ((Atomic Isotopic Mass-Mass Number)*(10^4))/Mass Number
Binding Energy Per Nucleon
​ Go Binding Energy per Nucleon = (Mass Defect*931.5)/Mass Number
Packing Fraction
​ Go Packing Fraction = Mass Defect/Mass Number
Mean Life Time
​ Go Mean Life Time = 1.446*Radioactive Half Life

## Number of Half Lives Formula

Number of Half Lives = Total Time/Half Life
n = ttotal/t1/2

## What is Half Life of Radioactive Substance ?

Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy).
