What is the density of carbon tetrachloride if a flask weighing 345.8 g is filled with 225 mL of the liquid, and the total weight of the flask and liquid is 703.55 g?

Rationale

1.59 g/mL

To find the density of carbon tetrachloride, we first calculate the mass of the liquid alone by subtracting the weight of the empty flask from the total weight. The density is then computed by dividing this mass by the volume of the liquid.

A (1.59 g/mL) CORRECT

This choice is correct. The mass of the carbon tetrachloride can be found by subtracting the weight of the empty flask (345.8 g) from the total weight (703.55 g), yielding a mass of 357.75 g. Dividing this mass by the volume (225 mL) gives a density of 1.59 g/mL.

B (2.76 g/mL) YOUR ANSWER

This choice is incorrect. If we were to calculate the density using this value, we would find that it implies a mass of approximately 621 g for 225 mL, which is inconsistent with the given total weight of the flask and liquid. Therefore, this density cannot be correct based on the provided data.

C (1.4 g/mL) YOUR ANSWER

This choice is also incorrect. Using this density suggests a mass of approximately 315 g for 225 mL, which again does not align with the calculated mass of the liquid (357.75 g). Thus, it does not accurately represent the density of carbon tetrachloride in this scenario.

D (None of the above) YOUR ANSWER

This choice is incorrect. Since we have already established that the density of carbon tetrachloride is 1.59 g/mL, it directly contradicts the assertion that none of the options provided are correct.

Conclusion

The calculated density of carbon tetrachloride, based on the provided mass and volume, is 1.59 g/mL. This value is essential for understanding the physical properties of carbon tetrachloride and determining its behavior in various applications. Other choices do not reflect accurate calculations based on the mass and volume given, confirming that option A is indeed the correct answer.

What is the density of carbon tetrachloride if a flask weighing 345.8 g is filled with 225 mL of the liquid, and the total weight of the flask and liquid is 703.55 g?

1.59 g/mL
