Relative Atomic Mass Solution

Follow our step by step solution on how to calculate Relative Atomic Mass?

FIRST Step Consider the formula

m = \frac{m c \cdot 12}{m c}

Next Step Substitute values of Variables

∴

m = \frac{12.011g \cdot 12}{12.011g}

Next Step Convert Units

∴

m = \frac{0.012kg \cdot 12}{0.012kg}

Next Step Prepare to Evaluate

∴

m = \frac{0.012 \cdot 12}{0.012}

LAST Step Evaluate

∴

m = 12
