Here's how to find the approximate location of the center of mass (CM) of the HCl molecule: Step 1: Define the masses and positions of the atoms. Let m_H be the mass of the hydrogen atom. Given that the chlorine atom is 35.5 times as massive as a hydrogen atom, the mass of the chlorine atom is m_Cl = 35.5 \, m_H. Let's place the hydrogen atom at the origin of our coordinate system, so its position is x_H = 0. The separation between the nuclei is r = 1.27 \, Å. Therefore, the position of the chlorine atom is x_Cl = 1.27 \, Å. Step 2: Use the formula for the center of mass of a two-particle system. The position of the center of mass (X_CM) for two particles along a line is given by: X_CM = m_H x_H + m_Cl x_Clm_H + m_Cl Step 3: Substitute the defined values into the formula. X_CM = m_H (0) + (35.5 \, m_H) (1.27 \, Å)m_H + 35.5 \, m_H X_CM = 0 + 35.5 × 1.27 \, m_H \, Å36.5 \, m_H The mass m_H cancels out: X_CM = 35.5 × 1.27 \, Å36.5 Step 4: Calculate the numerical value. X_CM = (45.085)/(36.5) \, Å X_CM ≈ 1.235 \, Å This value represents the distance of the center of mass from the hydrogen atom (our chosen origin). The approximate location of the CM of the molecule is 1.235 Å from the hydrogen atom. That's 2 down. 3 left today — send the next one.
