Nt(n) = ((1/2)^n)*N0
This formula uses 3 Variables
Variables Used
Amount of Substance Left After n Half Lives - (Measured in Kilogram) - Amount of substance left after n half lives is defined as the amount that is left after radioactive disintegration at time=t.
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.
Initial Concentration of Radioactive Substance - (Measured in Kilogram) - Initial Concentration of Radioactive Substance is defined as the amount of substance that is taken initially at time = 0 of the reaction.
STEP 1: Convert Input(s) to Base Unit
Number of Half Lives: 4 --> No Conversion Required
Initial Concentration of Radioactive Substance: 26 Atomic Mass Unit --> 4.31740452048404E-26 Kilogram (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Nt(n) = ((1/2)^n)*N0 --> ((1/2)^4)*4.31740452048404E-26
Evaluating ... ...
Nt(n) = 2.69837782530253E-27
STEP 3: Convert Result to Output's Unit
2.69837782530253E-27 Kilogram -->1.625 Atomic Mass Unit (Check conversion ​here)
1.625 Atomic Mass Unit <-- Amount of Substance Left After n Half Lives
