Gas from baking soda

Baking soda fizzes with an acid: $\text{NaHCO}_3 + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2\text{O} + \text{CO}_2$. You will make the program find the mass and the volume of carbon dioxide from a mass of baking soda, draw them as bars, and find the baking soda needed for a set volume.

The idea. $84\ \text{g}$ of baking soda gives one mole of carbon dioxide: $44\ \text{g}$, filling about $24\,000\ \text{cm}^3$.

Your tasks.

1. In co2_mass, return the grams of carbon dioxide from m grams of baking soda.
2. In co2_volume, return the volume in cm³.
3. Find needed, the grams of baking soda that give $600\ \text{cm}^3$ of gas.
