Number of Half Lives Solution

Follow our step by step solution on how to calculate Number of Half Lives?

FIRST Step Consider the formula

n = \frac{t total}{t 1/2}

Next Step Substitute values of Variables

∴

n = \frac{480000s}{0.0034Year}

Next Step Convert Units

∴

n = \frac{480000s}{107293.6368s}

Next Step Prepare to Evaluate

∴

n = \frac{480000}{107293.6368}

Next Step Evaluate

∴

n = 4.47370425978514

LAST Step Rounding Answer

∴

n = 4.4737
