Amount of Substance Left after Two Half Lives Solution

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

FIRST Step Consider the formula

N t(2) = (\frac{N 0}{4})

Next Step Substitute values of Variables

∴

N t(2) = (\frac{26u}{4})

Next Step Convert Units

∴

N t(2) = (\frac{4.3E-26kg}{4})

Next Step Prepare to Evaluate

∴

N t(2) = (\frac{4.3E-26}{4})

Next Step Evaluate

∴

N t(2) = 1.07935113012101E-26kg

LAST Step Convert to Output's Unit

∴

N t(2) = 6.5u
