Final answer:
The density of an object with a mass of 6.97g and a volume displacement from 4.63mL to 14.16mL is 0.73 g/mL. This is calculated by subtracting the initial water volume from the final volume to find the volume of the object, and then dividing the object's mass by this volume.
Step-by-step explanation:
To calculate the density of an object, you need its mass and its volume. The volume of the object can be found by measuring the volume of water it displaces when submerged. In this case, the object has a mass of 6.97g. The initial volume of water is 4.63mL, and it increases to 14.16mL after submerging the object. The volume displaced by the object is the difference between those two measurements, which is 14.16mL - 4.63mL = 9.53mL.
Density is mass divided by volume. Using the given figures:
Density = Mass / Volume
= 6.97g / 9.53mL
= 0.73 g/mL
This value does not match any of the options provided which indicates there may be an error. However, if 'a' is a typo and should read 0.73 g/mL, then this would be the correct answer. Otherwise, please recheck the question and options given, and the calculations to ensure accuracy.
