Age of Minerals and Rocks Solution

STEP 0: Pre-Calculation Summary

Formula Used

Age of Mineral and Rocks = Total Number of Radiogenic Lead Atom/((1.54*(10^(-10))*Number of U-238 present in Mineral/Rock Sample)+(4.99*(10^(-11))*Number of Th-232 present in Mineral/Rock Sample))
t_rock/mineral = M_{(Pb-206 + Pb-208)}/((1.54*(10^(-10))*U²³⁸)+(4.99*(10^(-11))*Th²³²))
This formula uses 4 Variables

Variables Used

Age of Mineral and Rocks - (Measured in Year) - Age of Mineral and Rocks is defined as the amount of time that has passed since the creation of the sample mineral/rock.
Total Number of Radiogenic Lead Atom - (Measured in Kilogram) - Total Number of Radiogenic Lead Atom is defined as the total mixture of lead-206 and lead-208 present in the mineral/rock sample.
Number of U-238 present in Mineral/Rock Sample - (Measured in Kilogram) - Number of U-238 present in Mineral/Rock Sample is defined as the amount of uranium-238 present in a given mineral/rock sample.
Number of Th-232 present in Mineral/Rock Sample - (Measured in Kilogram) - Number of Th-232 present in Mineral/Rock Sample is defined as the amount of thorium-232 present in a given mineral/rock sample.

STEP 1: Convert Input(s) to Base Unit

Total Number of Radiogenic Lead Atom: 0.08 Milligram --> 8E-08 Kilogram (Check conversion here)
Number of U-238 present in Mineral/Rock Sample: 2 Milligram --> 2E-06 Kilogram (Check conversion here)
Number of Th-232 present in Mineral/Rock Sample: 0.0005 Milligram --> 5E-10 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_rock/mineral = M_{(Pb-206 + Pb-208)}/((1.54*(10^(-10))*U²³⁸)+(4.99*(10^(-11))*Th²³²)) --> 8E-08/((1.54*(10^(-10))*2E-06)+(4.99*(10^(-11))*5E-10))

Evaluating ... ...

t_rock/mineral = 259719220.796887

STEP 3: Convert Result to Output's Unit

8.19594698416476E+15 Second -->259719220.796887 Year (Check conversion here)

FINAL ANSWER

259719220.796887 ≈ 2.6E+8 Year <-- Age of Mineral and Rocks

How to Determine the Age using Radioactive isotopes?

Each radioactive isotope decays with a characteristic rate which is invariable under all conditions of temperature, pressure and chemical environment. However, radioactivity being a statistical phenomenon, the invariability of the decay constant is assured only as long as large number of atoms are present; with this provision, radioisotopes can be looked upon as nature's atomic clocks recording the passage of time since the birth of the universe in terms of number of atoms decayed.
The basis of age determination by radioactive method depends on the the sample containing a radioisotope in equilibrium with it's stable product and of an age commensurate with the half-life.
