If you write the formula wrong, then you will calculate the formula weight wrong (too many or too few of one atom in a formula will translate to an incorrect formula weight). Then, when you try to figure out how many moles of the compound you have, your moles will be wrong too. And THEN, if you try to work out the stoichometry of a reaction using the incorrect formula, your mole RATIOS will be wrong, and thus you will get a wrong number when you try to determine the expected yield of a product in a reaction. (Not to mention it probably won't balance with an incorrect formula). If you're making up a solution using a wrong number of moles (see above), your molarity (moles per liter solution) will be wrong too. Everything will be wrong if you don't get your chemical formula right!

Because each chemical formula has a different outcome, so if you write the wrong chemical formula for that specific problem, you will have the wrong outcome.

The formula tells you the correct ratio of each element in the compound. Any questions that involve "how much" will require you to know and use this proper ratio. Combinations of the same elements but in different ratios produce compounds with different properties. Ex. water, H20 and hydrogen peroxide H2O2. You wouldn't want to wash your hair with peroxide or use it to quench your thirst!
Correct formulas are also needed to balance chemical equations so again, you know "how much" of each substance to use and "how much" of each product you get.

So you know the chemical makeup of the substance.
