1. How many molecules are contained in each compound? a. 1.35 mol of carbon disulfide (CS_(2)) b. 0.254 mol of diarsenic trioxide (As_(2)O_(3)) c. 1.25 mol of water d. 150.0 mol of HCl

To determine the number of molecules in each compound, we need to use Avogadro's number, which is molecules per mole.Let's calculate the number of molecules for each compound:a. **1.35 mol of carbon disulfide (CS₂)** b. **0.254 mol of diarsenic trioxide (As₂O₃)** c. **1.25 mol of water (H₂O)** d. **150.0 mol of HCl** So, the number of molecules contained in each compound is:a. molecules of CS₂b. molecules of As₂O₃c. molecules of H₂Od. molecules of HCl
