Amount of Substance Left after Three Half Lives Solution

Follow our step by step solution on how to calculate Amount of Substance Left after Three Half Lives?

FIRST Step Consider the formula

N t(3) = \frac{N 0}{8}

Next Step Substitute values of Variables

∴

N t(3) = \frac{26u}{8}

Next Step Convert Units

∴

N t(3) = \frac{4.3E-26kg}{8}

Next Step Prepare to Evaluate

∴

N t(3) = \frac{4.3E-26}{8}

Next Step Evaluate

∴

N t(3) = 5.39675565060505E-27kg

LAST Step Convert to Output's Unit

∴

N t(3) = 3.25u
