A flask that weighs 345.8 g is filled with 225 mL of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 703.55 g. From this information, calculate the density of carbon tetrachloride.

Rationale

Density of carbon tetrachloride is 1.59 g/mL.

To calculate the density, we first determine the mass of carbon tetrachloride by subtracting the weight of the empty flask from the total weight. The mass of carbon tetrachloride is 703.55 g - 345.8 g = 357.75 g. Density is then calculated using the formula density = mass/volume, so density = 357.75 g / 225 mL, which equals approximately 1.59 g/mL.

A (1.59 g/mL) CORRECT

This choice correctly represents the calculated density of carbon tetrachloride. Using the mass of 357.75 g and the volume of 225 mL, the density calculation yields precisely 1.59 g/mL, confirming this option as correct.

B (2.76 g/mL) YOUR ANSWER

This value does not match the calculated density. If we assume this density, the mass would have to be 2.76 g/mL × 225 mL = 621 g, which exceeds the actual mass of carbon tetrachloride (357.75 g). Hence, this option is incorrect.

C (1.4 g/mL) YOUR ANSWER

This option also fails to match our calculations. Using a density of 1.4 g/mL, the mass would be 1.4 g/mL × 225 mL = 315 g, which is significantly lower than the actual mass of carbon tetrachloride (357.75 g). Therefore, this choice is incorrect.

D (None are correct.) YOUR ANSWER

This option is invalid since we have confirmed that the density of carbon tetrachloride is indeed 1.59 g/mL, making this statement false.

Conclusion

The density of carbon tetrachloride can be accurately determined using the mass and volume provided in the question. The calculation leads to a density of 1.59 g/mL, which aligns perfectly with choice A. The other options either miscalculate or misrepresent this value, reinforcing that choice A is the only correct answer.
