**Locating the Center of Mass of Molecules** 6) Locate the center of mass of the following molecules: (a) The HCl molecule has a dumbbell shape, as shown below, with the atoms separated by \(1.30 \times 10^{-10}\) m. The mass of the H atom is 1 u and that of the Cl atom is 35 u. (b) The H\(_2\)O molecule is also shown below. The mass of the O atom is 16 u. The H and O atoms are separated by \(1 \times 10^{-10}\) m and the bond angle is 105°. **Diagrams:** The diagrams depict molecular structures: - For HCl: The H atom and Cl atom are connected linearly, resembling a dumbbell. - For H\(_2\)O: The molecule has a bent shape with two hydrogen atoms bonded to an oxygen atom, forming a \(105^\circ\) angle between the hydrogen atoms. These visual representations help in understanding the geometric arrangement of the atoms, crucial for locating the center of mass.

**Physics Problem Flow Chart** 1. **Draw a Picture** - Label which directions are positive (x- and y-), and label relevant quantities on the diagram. 2. **Draw a Second Picture...** - If you have BEFORE/AFTER situations, force additions, vector component diagrams, etc. 3. **Identify Explicitly Given Values** - Write all given actual numbers in terms of variables. For previously calculated values, use values before rounding for significant figures. 4. **Identify Implicitly Given Values** - Wording that implies specific values: e.g., “at rest”, “comes to a stop”, “dropped”, “smooth surface”, “constant velocity”. 5. **Identify Required Quantity and Type of Problem** - Look for keywords like “when”, “how far”, “how fast”, etc. Determine the type of problem from the quantities given or sought. 6. **Calculate/Convert Easily Derived Quantities** - For example, the x- and y-components of velocity/force vectors, or the force of gravity given the mass. 7. **Find Relevant Equation(s)** - Look for one that links the given quantities to the quantity you need to find. 8. **Find a Second Equation...** - If you’re missing a quantity needed to use an equation, draw up a plan on how to link the equations and quantities. 9. **Solve for the Quantity Without Using Numbers** - First, cancel any quantities that are zero. Use algebra to isolate the quantity you need on one side of the equals sign. Check with dimensional analysis. 10. **Sub in Numbers on Paper** - Ensure units of each number are correct before you substitute values into the equations. 11. **Use Calculator to Find Value** - Use as few presses of the “=” or “ENTER” button as possible. Keep extra significant figures until the next step. 12. **Write Conclusion Statement with Correct Sig Figs** - In plain English, with correct units.
