A small flask has a mass of 22.71 g. When it is filled with water the total mass is 153.38 g. When it is filled with milk the total mass is 157.67 g. What is the density of milk?

1.03

To find the density of milk, we need to divide the mass of the milk by its volume.

First, we need to calculate the volume of the flask. Since the mass of the flask is 22.71 g, we can assume that is the mass of the empty flask, without any liquid.

When the flask is filled with water, the total mass is 153.38 g. Subtracting the mass of the empty flask, we get the mass of the water: 153.38 g - 22.71 g = 130.67 g.

When the flask is filled with milk, the total mass is 157.67 g. Subtracting the mass of the empty flask, we get the mass of the milk: 157.67 g - 22.71 g = 134.96 g.

Now, we can calculate the density of milk by dividing the mass of the milk by the volume of the flask.

Density = Mass / Volume

Density of milk = Mass of milk / Volume of flask

Volume of flask = Volume of water = Mass of water / Density of water

Since water has a known density of 1 g/mL or 1 g/cm^3, we can substitute it in the formula.

Volume of flask = 130.67 g / 1 g/mL = 130.67 mL

Now we can calculate the density of milk:

Density of milk = 134.96 g / 130.67 mL ≈ 1.031 g/mL

Therefore, the density of milk is approximately 1.031 g/mL.

Let v be the volume of the flask.

densitywater= 1g/cm^3 you can be more accurate than that.
So, find the volume of water:

volume=mass/density=(153.38-22.71)g/1g/cm^3 you figure that out.

density milk= (157.67-22.71)g/volumeabove
