Determination of Age of Minerals and Rocks using Rubidium-87/ Strontium Method Solution

Follow our step by step solution on how to calculate Determination of Age of Minerals and Rocks using Rubidium-87/ Strontium Method?

FIRST Step Consider the formula

t = \frac{1}{λ} \cdot (\frac{R Sr-87:Sr-86 - R° Sr-87:Sr-86}{R Rb-87:Sr-86})

Next Step Substitute values of Variables

∴

t = \frac{1}{1.4E-111/Year} \cdot (\frac{0.7025 - 0.701}{0.0025})

Next Step Convert Units

∴

t = \frac{1}{4.5E-191/s} \cdot (\frac{0.7025 - 0.701}{0.0025})

Next Step Prepare to Evaluate

∴

t = \frac{1}{4.5E-19} \cdot (\frac{0.7025 - 0.701}{0.0025})

Next Step Evaluate

∴

t = 1.33339233802822E+18s

Next Step Convert to Output's Unit

∴

t = 42253521126.7622Year

LAST Step Rounding Answer

∴

t = 4.2E+10Year
