Pressure by Ideal Gas Law Solution

Follow our step by step solution on how to calculate Pressure by Ideal Gas Law?

FIRST Step Consider the formula

P gas = \frac{N moles \cdot [R] \cdot T gas}{V}

Next Step Substitute values of Variables

∴

P gas = \frac{0.99 \cdot [R] \cdot 273K}{22.4L}

Next Step Substitute values of Constants

∴

P gas = \frac{0.99 \cdot 8.3145 \cdot 273K}{22.4L}

Next Step Convert Units

∴

P gas = \frac{0.99 \cdot 8.3145 \cdot 273K}{0.0224m³}

Next Step Prepare to Evaluate

∴

P gas = \frac{0.99 \cdot 8.3145 \cdot 273}{0.0224}

Next Step Evaluate

∴

P gas = 100319.188027155Pa

LAST Step Rounding Answer

∴

P gas = 100319.188Pa
