*THE EXPLANATION*
Lacy obtained a dry empty flask with a stopper and placed it on an analytical balance. She found the mass to be 36.765 g. Lacy then completely filled the flask with distilled water and forced all the air out with the stopper. she again weighed the stopper, flask, and water and obtained a mass of 65.264 g. she determined the volume of the flask she emptied and dried her flask and obtained the unknown liquid she completely filled the flask with her unknown liquid placed the stopper on as before and obtained a mass of 59.323 g
1) mass of the empty flask plus stopper
2) mass of stoppered flask plus water
3) mass of stoppered flask plus unknown liquid
4) mass of water
5)temperature in the lab
6) volume of flas (density of h20 at 25 degrees c 0.09970 g/cm^3 at 20 degrees c 0.9982 g/cm^3)
7) mass of liquid
8) density of liquid

1) The mass of the empty flask plus stopper is 36.765 g.

2) The mass of the stoppered flask plus water is 65.264 g.

3) The mass of the stoppered flask plus unknown liquid is 59.323 g.

4) To find the mass of water, we subtract the mass of the empty flask plus stopper from the mass of the stoppered flask plus water:
Mass of water = (Mass of stoppered flask plus water) - (Mass of empty flask plus stopper)
Mass of water = 65.264 g - 36.765 g
Mass of water = 28.499 g

5) The temperature in the lab is not provided in the given information.

6) To find the volume of the flask, we can use the density of water at 25 degrees Celsius, which is 0.9970 g/cm^3:
Volume of flask = Mass of water / Density of water at 25 degrees Celsius
Volume of flask = 28.499 g / 0.9970 g/cm^3
Volume of flask = 28.64 cm^3

7) To find the mass of the liquid, we subtract the mass of the empty flask plus stopper from the mass of the stoppered flask plus unknown liquid:
Mass of liquid = (Mass of stoppered flask plus unknown liquid) - (Mass of empty flask plus stopper)
Mass of liquid = 59.323 g - 36.765 g
Mass of liquid = 22.558 g

8) To find the density of the liquid, we divide the mass of the liquid by the volume of the flask:
Density of liquid = Mass of liquid / Volume of flask
Density of liquid = 22.558 g / 28.64 cm^3

To find the answers to the given questions, we will use the information provided in the problem.

1) The mass of the empty flask and the stopper is given as 36.765 g.

2) The mass of the stoppered flask plus water is given as 65.264 g. To find the mass of water, we need to subtract the mass of the empty flask and stopper from the total mass. Therefore, to find the mass of water, we can use the following calculation:

Mass of water = Mass of stoppered flask plus water - Mass of empty flask and stopper
Mass of water = 65.264 g - 36.765 g

3) The mass of the stoppered flask plus the unknown liquid is given as 59.323 g. To find the mass of the liquid, we need to subtract the mass of the empty flask and stopper from the total mass. Therefore, to find the mass of the liquid, we can use the following calculation:

Mass of liquid = Mass of stoppered flask plus unknown liquid - Mass of empty flask and stopper
Mass of liquid = 59.323 g - 36.765 g

4) The mass of the water can be obtained by using the answer for question 2.

5) The problem does not provide any information about the temperature in the lab, so we cannot determine it from the given information.

6) The density of water at 25 degrees Celsius is given as 0.09970 g/cm^3. To find the volume of the flask, we can use the following equation:

Density = Mass / Volume

We know the density and the mass of the water, so we can rearrange the equation to solve for volume:

Volume = Mass / Density

7) The mass of the liquid can be obtained by using the answer for question 3.

8) The density of the liquid can be calculated by dividing the mass of the liquid by the volume of the flask obtained in question 6.

Now you have the steps to find the answers to the given questions.
