# How many grams of sodium are in 3 moles of sodium carbonate?

The molecular mass of $N {a}_{2} C {O}_{3}$ is $105.99 \cdot g \cdot m o {l}^{-} 1$. This is composed of $2 \times 22.99 \cdot g \left(N a\right) + 12.011 \cdot g \left(C\right) + 3 \times 15.999 \cdot g \left(O\right)$.
If there are $3$ $m o l$, there are $3 \times 2 \times 22.99 \cdot g$ $N a$ $=$ ??g
