How to Calculate Moles from Atoms in Chemistry
How many moles are in 4.28 x 10^23 atoms of carbon?
Answer: 0.711 moles C
Answer:
To calculate the number of moles from atoms in chemistry, you can use the concept of Avogadro's Number, which is 6.022 × 10²³ atoms. Here is the step-by-step guide:
Explanation:
Step 1: Define
[Given] 4.28 × 10²³ atoms C
[Solve] moles C
Step 2: Identify Conversions
Avogadro's Number
Step 3: Convert
[DA] Set up: 4.28 × 10²³ atoms C x (1 mol C / 6.022 × 10²³ atoms C)
[DA] Divide [Cancel out units]: 0.710727 moles C
Step 4: Check
Follow sig fig rules and round. We are given 3 sig figs.
0.710727 moles C ≈ 0.711 moles C
