Calculate the number of Li atoms in 3.1 mol of Li. Express your answer using two significant figures. 195] ΑΣΦ Submit Previous Answers Request Answer Part B [y] ? X Incorrect; Try Again; 5 attempts remaining Multiplying the number of moles of an atom by its atomic mass in g/mol results in the quantity in g. To convert to the quantity in atoms, start with the equality 6.022 x 1023 atoms of Li = 1 mol of Li and use this to create a conversion factor such that the units of mol cancel out, leaving atoms. Since there are many atoms in a mole, you should expect the number of atoms to be large. Submit Calculate the number of CO₂ molecules in 0.0920 mol of CO₂.

**Educational Exercise: Calculating the Number of Atoms and Molecules** --- **Exercise** Calculate the number of Li atoms in 3.1 mol of Li. *Express your answer using two significant figures.* [Input Box] atoms of Li [Buttons: Submit, Previous Answers, Request Answer] **Feedback Message:** Incorrect; Try Again; 5 attempts remaining. Multiplying the number of moles of an atom by its atomic mass in g/mol results in the quantity in g. To convert the quantity in atoms, start with the equality 6.022 x 10²³ atoms of Li = 1 mol of Li and use this to create a conversion factor such that the units of mol cancel out, leaving atoms. Since there are many atoms in a mole, you should expect the number of atoms to be large. --- **Part B** Calculate the number of CO₂ molecules in 0.0920 mol of CO₂. *Express your answer using three significant figures.* [Input Box] molecules of CO₂ [Buttons: Submit, Request Answer] --- This exercise involves using Avogadro's number to convert moles to atoms and molecules. Remember to express your answer with the correct number of significant figures as specified.
