Specific Gas Constant Solution

Follow our step by step solution on how to calculate Specific Gas Constant?

FIRST Step Consider the formula

R = \frac{[R]}{M molar}

Next Step Substitute values of Variables

∴

R = \frac{[R]}{44.01g/mol}

Next Step Substitute values of Constants

∴

R = \frac{8.3145}{44.01g/mol}

Next Step Convert Units

∴

R = \frac{8.3145}{0.044kg/mol}

Next Step Prepare to Evaluate

∴

R = \frac{8.3145}{0.044}

Next Step Evaluate

∴

R = 188.922122657424J/(kg*K)

LAST Step Rounding Answer

∴

R = 188.9221J/(kg*K)
