# What is the mass of 1.00 mol of sodium hydrogen carbonate?

Approx. $84.00 \cdot g \cdot m o {l}^{-} 1$
Summing up the atomic masses for 1 mol $N a H C {O}_{3}$, there are $22.99 \cdot g$ sodium $+$ $1.008 \cdot g$ hydrogen $+$ $3 \times 16.00 \cdot g$ oxygen $+$ $12.0 \cdot g$ carbon $=$ $84.0 \cdot g \cdot m o {l}^{-} 1$.
