Tips to approach solution stoichiometry

Just follow these 4 steps.

1. Balance the chemical equation ( And make sure the charges make sense as well )

2. Use $C = \frac{n}{V}$ $\iff n = CV$ to get the amount of the substance

3. TO keep consistent and make sure to never make an unit area, always keep in $dm^3$, decimeter cubed.

4. Use the basis of stoichiometry/mole ratios in other to find the amount of other substances.
