Solution Steps

Step 1: Determine the Total Mass of the Sample

The total mass of the sample is given as 24.0 g.

Step 2: Identify the Mass of Chlorine

The mass of chlorine (Cl) in the sample is given as 14.6 g.

Step 3: Calculate the Percent Composition of Chlorine

The percent composition of chlorine is calculated using the formula: \[ \text{Percent composition of Cl} = \left( \frac{\text{Mass of Cl}}{\text{Total mass of sample}} \right) \times 100 \] Substitute the given values: \[ \text{Percent composition of Cl} = \left( \frac{14.6 \, \text{g}}{24.0 \, \text{g}} \right) \times 100 \]

Step 4: Perform the Calculation

\[ \text{Percent composition of Cl} = \left( \frac{14.6}{24.0} \right) \times 100 \approx 60.8333\% \]

Step 5: Round to Three Significant Figures

Round the result to three significant figures: \[ \text{Percent composition of Cl} \approx 60.8\% \]

Final Answer

\[ \boxed{60.8\%} \]

Consider a situation in which a flask is half-filled with liquid water at room temperature. The partially filled flask is then sealed and given time to reach equilibrium. Which of the following statements are true? [Select all that apply.] Once the flask reaches equilibrium the rate at which water molecules move from the liquid to the gas phase is equal to the rate at which water molecules move, from the gas to the liquid phase. If given enough time, the water will evaporate completely. After the flask reaches equilibrium, there will no longer be any movement of individual water molecules from the gas phase into the liquid phase. After the flask reaches equilibrium, there will no longer be any movement of individual water molecules from the liquid phase into the gas phase. The rate of condensation decreases as the flask approaches equilibrium. The rate of condensation increases as the flask approaches equilibrium. The vapor pressure of the water is the total pressure in the flask after it reaches equilibrium. The vapor pressure of the water is the partial pressure of water (Pwater) in the flask after it reaches equilibrium.

Joel assumes that the average predicted high in Destin will be 10° warmer than the average predicted high in Kingsport for Sunday through Thursday. In the table below, predicted daily high temperatures are indicated with H, while predicted daily low temperatures are indicated with L. - Sunday - Kingsport, TN: H:68, L: 40 - Destin, FL: H:84, L: 65 - Monday - Kingsport, TN: H: 72, L: 41 - Destin, FL: H:82, L:60 - Tuesday - Kingsport, TN: H: 73, L: 45 - Destin, FL: H: 78, L: 64 - Wednesday - Kingsport, TN: H: 75, L: 48 - Destin, FL: H:80, L:66 If the predicted high in Kingsport is 72° on Thursday, what would Thursday's predicted high for Destin need to be for Joel's assumption to be correct?

A swimming pool holds 480,000 liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe alone can empty it in 120 minutes, and the second pipe alone can empty it in 240 minutes. When both pipes are draining together, how long does it take them to empty the pool? minutes
