Molecular Weight of Gas by Ideal Gas Law Solution

Follow our step by step solution on how to calculate Molecular Weight of Gas by Ideal Gas Law?

FIRST Step Consider the formula

M molar = \frac{m gas \cdot [R] \cdot T gas}{P gas \cdot V}

Next Step Substitute values of Variables

∴

M molar = \frac{44g \cdot [R] \cdot 273K}{101325Pa \cdot 22.4L}

Next Step Substitute values of Constants

∴

M molar = \frac{44g \cdot 8.3145 \cdot 273K}{101325Pa \cdot 22.4L}

Next Step Convert Units

∴

M molar = \frac{0.044kg \cdot 8.3145 \cdot 273K}{101325Pa \cdot 0.0224m³}

Next Step Prepare to Evaluate

∴

M molar = \frac{0.044 \cdot 8.3145 \cdot 273}{101325 \cdot 0.0224}

Next Step Evaluate

∴

M molar = 0.0440032625609146kg/mol

Next Step Convert to Output's Unit

∴

M molar = 44.0032625609146g/mol

LAST Step Rounding Answer

∴

M molar = 44.0033g/mol
