When you calculate molar mass, there are some common mistakes to watch out for. These are easy to make, so let’s go through them!
Using Wrong Atomic Masses: One big mistake is using old or rounded atomic masses. Always look at a reliable periodic table to get the most accurate numbers!
Counting Atoms Incorrectly: When you see a chemical formula, like H₂O, make sure to check the small numbers (called subscripts). It’s easy to miscount, especially in formulas with parentheses!
Forgetting About the Whole Compound: If you’re calculating for something like C₂H₆O, remember to include every atom in that formula. You need to add up each type of atom correctly.
Skipping Units: Sometimes people forget to write the units or mix them up. Molar mass is usually shown in grams per mole (g/mol), so keep that clear!
Hurrying Through Calculations: Many mistakes happen when you rush. Take your time to check each step, because this helps catch simple errors that can mess up your answer.
Just remember to be careful and take your time. With practice, you’ll get really good at finding molar mass!
