It looks long but I just have two questions:
mass of empty flask with stopper = 32.634 g
mass of flask with water and stopper = 59.479 g
density of the water = 0.9973 g/cm^3
mass of water = 26.845 g
volume of water = 26.918 cm^3
the flask is then emptied and an unknown substance is added
mass of flask with new liquid and stopper = 23.531 g
density of liquid = 0.46710 g/cm^3
the flask is emptied again and dried
pieces of metal were added
weight of stoppered flask and its metal contents = 152.047 g
then filled with water and mass = 165.541
mass of metal = 13.494
mass of water = 13.494
Is the mass of metal and water suppose to be the same?
Can anyone tell me the volume of the water?
What is the volume of the metal?
What is the density of the volume?
Can you show the work? Thanks.

The question does not make a sense. I just copy it here:
"mass of empty flask with stopper = 32.634 g
mass of flask with water and stopper = 59.479 g
density of the water = 0.9973 g/cm^3
mass of water = 26.845 g
volume of water = 26.918 cm^3
the flask is then emptied and an unknown substance is added"
OK so far, then:
"mass of flask with new liquid and stopper = 23.531 g"
Wait! this is in contradition with the first sentence!
"density of liquid = 0.46710 g/cm^3
the flask is emptied again and dried
pieces of metal were added
weight of stoppered flask and its metal contents = 152.047 g
then filled with water and mass = 165.541
mass of metal = 13.494"
Wait!! Another contradition here--how can the mass of metal to be only 13.494 (g)?
"mass of water = 13.494
Is the mass of metal and water suppose to be the same?
Can anyone tell me the volume of the water?
What is the volume of the metal?
What is the density of the volume?"
Wait!!! What do you mean about "the density of the volume"?
