Although multiple values are given, our focus is on HCl.
<span>We have 215 mL (0.215 L) of 0.300 M HCl fully consumed in the reaction. It's important to recall that the number of moles is found by multiplying volume by molarity:</span>
moles = 0.215 L × 0.300 M
<span>moles = 0.0645 moles of HCl</span>
The stated condition has been verified. Construct the resonance structure for CSO, where the central atom carries a +2 formal charge and the oxygen atom has a +1 charge. We need to create the resonance structure for CSO as shown in the figure. According to the problem, there is a +2 formal charge on the central atom and a +1 charge on the oxygen atom. The central atom in this structure is sulfur. We will calculate the formal charge of sulfur based on the information presented, demonstrating that it aligns with the necessary formal charges.
