Transcript text: If grams of a substance are given, will you use Avogadro's as your first step?
Solution
Solution Steps
Step 1: Determine the Context
Identify the context of the problem. If the problem involves converting grams of a substance to moles or atoms/molecules, Avogadro's number may be relevant.
Step 2: Convert Grams to Moles
If the task is to convert grams to moles, use the molar mass of the substance as the first step. This involves dividing the given mass by the molar mass of the substance.
Step 3: Use Avogadro's Number
If the task requires finding the number of atoms or molecules, use Avogadro's number (\(6.022 \times 10^{23}\)) after converting grams to moles. Multiply the number of moles by Avogadro's number to find the number of particles.
