Volume of Monolayer Gas by BET Equation Solution

Follow our step by step solution on how to calculate Volume of Monolayer Gas by BET Equation?

FIRST Step Consider the formula

V mono = \frac{(P v - (\frac{P v}{P 0})) \cdot (1 + (C \cdot (\frac{P v}{P 0}))) - (\frac{P v}{P 0}) \cdot V total}{C \cdot (\frac{P v}{P 0})}

Next Step Substitute values of Variables

∴

V mono = \frac{(6Pa - (\frac{6Pa}{21Pa})) \cdot (1 + (2 \cdot (\frac{6Pa}{21Pa}))) - (\frac{6Pa}{21Pa}) \cdot 998L}{2 \cdot (\frac{6Pa}{21Pa})}

Next Step Convert Units

∴

V mono = \frac{(6Pa - (\frac{6Pa}{21Pa})) \cdot (1 + (2 \cdot (\frac{6Pa}{21Pa}))) - (\frac{6Pa}{21Pa}) \cdot 0.998m³}{2 \cdot (\frac{6Pa}{21Pa})}

Next Step Prepare to Evaluate

∴

V mono = \frac{(6 - (\frac{6}{21})) \cdot (1 + (2 \cdot (\frac{6}{21}))) - (\frac{6}{21}) \cdot 0.998}{2 \cdot (\frac{6}{21})}

Next Step Evaluate

∴

V mono = 15.2152857142857m³

Next Step Convert to Output's Unit

∴

V mono = 15215.2857142857L

LAST Step Rounding Answer

∴

V mono = 15215.2857L
