Question
**Question:** How many Ba atoms are there in 3.39 moles of Ba? [Input Box] atoms --- **Explanation:** This is a question often found in chemistry courses related to mole-to-atom conversions. You can use Avogadro's number (approximately \(6.022 \times 10^{23}\)) to convert moles of a substance to the number of atoms. Simply multiply the number of moles by Avogadro’s number to get the number of atoms. **Formula:** \[ \text{Number of atoms} = \text{moles} \times \text{Avogadro's number} \] For this specific question: \[ \text{Number of Ba atoms} = 3.39 \, \text{moles} \times 6.022 \times 10^{23} \, \text{atoms/mole} \]

**Question:** How many moles of Ti are there in a sample of Ti that contains \(2.49 \times 10^{24}\) atoms? [ ] moles --- To solve this, use Avogadro's number, which is \(6.022 \times 10^{23}\) atoms/mole. Divide the number of atoms by Avogadro's number to find the number of moles: \[ \text{Moles of Ti} = \frac{2.49 \times 10^{24} \text{ atoms}}{6.022 \times 10^{23} \text{ atoms/mole}}. \]
