To calculate the density of mercury, you need to use the formula:
Density = Mass / Volume
Given that the mass of the density bottle when full of mercury is 360 grams, and assuming the volume remains constant, we just need to determine the volume of the density bottle when it is completely filled with mercury.
First, let's determine the mass of the empty density bottle. From the given information, we know that the mass is 20 grams when empty.
Next, we'll determine the mass of the water-filled density bottle. The mass is 45 grams when full of water.
Using these values, we can subtract the mass of the empty density bottle from the mass of the water-filled density bottle to find the mass of the water:
Mass of water = Mass when full of water - Mass when empty
Mass of water = 45 g - 20 g
Mass of water = 25 g
Now, we'll determine the volume of the water-filled density bottle. We can assume that the volume of the water-filled density bottle is equal to the volume of the bottle when it is filled with mercury.
Finally, we'll calculate the density of mercury using the formula:
Density = Mass of mercury / Volume
Density of mercury = 360 g / Volume
Since the volume is the same for both the water-filled density bottle and the mercury-filled density bottle, we can replace the volume with the volume of water:
Density of mercury = 360 g / Volume of water
For a more accurate calculation of density, you will need to measure the volume of water directly using a graduated cylinder or any other appropriate measuring instrument. Once you have that value, you can substitute it into the formula to calculate the density of mercury.
