Relative Molecular Mass of Compound Solution

Follow our step by step solution on how to calculate Relative Molecular Mass of Compound?

FIRST Step Consider the formula

M r = \frac{M molecule}{\frac{1}{12} \cdot M C-12}

Next Step Substitute values of Variables

∴

M r = \frac{18.0153g}{\frac{1}{12} \cdot 12.0116g}

Next Step Convert Units

∴

M r = \frac{0.018kg}{\frac{1}{12} \cdot 0.012kg}

Next Step Prepare to Evaluate

∴

M r = \frac{0.018}{\frac{1}{12} \cdot 0.012}

Next Step Evaluate

∴

M r = 17.9978820473542

LAST Step Rounding Answer

∴

M r = 17.9979
