Final answer:
Theoretical density can be calculated using mass and volume obtained from buret readings using the formula Density = Mass/Volume, ensuring that significant figures from the readings are accounted for in the final answer.
Step-by-step explanation:
The theoretical density of an object can be calculated from buret readings if the buret is used to measure the volume of fluid displaced by the object. Density is defined as mass per unit volume. Assuming you have followed the simulation instructions and used the water displacement method to measure the mass and volume of the green block, you can apply the formula for density (Density = Mass/Volume).
For example, if the green block displaced water in the buret by a certain volume reading, and you know the mass of the block from the simulation, you divide the mass by the volume to get the density of the block. Remember to record the buret readings carefully to get accurate measurements. When performing the calculations, make sure to consider the number of significant figures in the readings to report your answer with the correct precision.
