16.6ml of a solution is run into an empty flask. the mass of the flask is 145.0 g. the mass of the flask plus solution is 158.5 g. what is the density of the solution?
mass of solution = 158.5 - 145.0 = ?
Then density = mass/volume
To find the density of the solution, we need to divide the mass of the solution by its volume.
The mass of the solution can be determined by subtracting the mass of the empty flask from the mass of the flask plus solution:
Mass of solution = Mass of flask + solution - Mass of empty flask
= 158.5 g - 145.0 g
= 13.5 g
Now, we have the mass of the solution. To find the volume of the solution, we can assume that the volume of the solution is equal to the volume of the flask, which is given as 16.6 mL.
Density = Mass / Volume
= 13.5 g / 16.6 mL
To convert mL to g, we can use the density of water (1 g/mL, approximately).
Density = 13.5 g / 16.6 mL * (1 mL / 1 g)
= 13.5 g / 16.6 g
≈ 0.814 g/mL
Therefore, the density of the solution is approximately 0.814 g/mL.
