Critical Compressibility Solution

Follow our step by step solution on how to calculate Critical Compressibility?

FIRST Step Consider the formula

z = \frac{P c \cdot V cr \cdot 10^{- 3}}{R \cdot T c}

Next Step Substitute values of Variables

∴

z = \frac{3.4E+7Pa \cdot 6L \cdot 10^{- 3}}{0.055J/(kg*K) \cdot 647K}

Next Step Convert Units

∴

z = \frac{3.4E+7Pa \cdot 0.006m³ \cdot 10^{- 3}}{0.055J/(kg*K) \cdot 647K}

Next Step Prepare to Evaluate

∴

z = \frac{3.4E+7 \cdot 0.006 \cdot 10^{- 3}}{0.055 \cdot 647}

Next Step Evaluate

∴

z = 5.64844737951384

LAST Step Rounding Answer

∴

z = 5.6484
