Molar mass is the weight of one mole of a substance. It's measured in grams per mole (g/mol).

Molar mass is important because it adds up the atomic weights of all the atoms in a molecule. This makes it really helpful when you need to make conversions.

Here’s why understanding molar mass matters in chemistry:

• Calculating Moles: Knowing the molar mass helps you easily switch between grams and moles.
• Stoichiometry: It’s key for balancing chemical equations and predicting how much product you'll get.
• Insight into Reactions: It helps you understand how different substances work together in a reaction based on their amounts.

In short, getting the hang of molar mass helps you solve chemical problems more effectively!
