Active Mass Solution

Follow our step by step solution on how to calculate Active Mass?

FIRST Step Consider the formula

M = \frac{w}{MW}

Next Step Substitute values of Variables

∴

M = \frac{21g}{120g}

Next Step Convert Units

∴

M = \frac{0.021kg}{0.12kg}

Next Step Prepare to Evaluate

∴

M = \frac{0.021}{0.12}

Next Step Evaluate

∴

M = 0.175mol/m³

Next Step Convert to Output's Unit

∴

M = 0.000175mol/L

LAST Step Rounding Answer

∴

M = 0.0002mol/L
