An empty relative density bottle weighs 25g.it weighs 65g when filled with a liquid and 75g when with water.caculate the density of the liquid.
Ww = 75-25 = 50 g = Wt of water.
Ww = V * D = 50 g.
V * 1g/cm^3 = 50
V = 50 cm^3. = Vol. of water.
65 - 25 = 40 g. = Wt. of the liquid.
D = 40g/50cm^3 = 0.80 g/cm^3. = Density of the liquid.
An empty density bottle weights 25g. When completely filled with water. It weighs 55g and when completely filled with a liquid. It weighs 52g. Calculate I. volume of the density bottle and II. density of liquid
Thanks you have really helped me alot
Ww=75-25=50g=wt of water ww=v*D=50g V*1g/cm^3=50 v=50cm^3=vol of water
65-25=40g=wt of the liquid D=40g/50cm^3=0.80g/cm^3=density of the liquid.
Not that bad

To calculate the density of the liquid, we need to know the mass and volume of the liquid. We can determine the mass of the liquid by finding the difference in mass between the bottle filled with the liquid and the empty bottle.
Given information:
- Empty bottle weight: 25g
- Bottle + liquid weight: 65g
- Bottle + water weight: 75g
Step 1: Determine the mass of the liquid.
The mass of the liquid can be calculated by finding the difference in mass between the bottle filled with the liquid and the empty bottle:
Mass of the liquid = (Bottle + liquid weight) - (Empty bottle weight)
Mass of the liquid = 65g - 25g
Mass of the liquid = 40g
Step 2: Determine the volume of the liquid.
To calculate density, we need both mass and volume. However, we are not given the volume of the liquid directly. However, because we know the density of water, we can use that information to find the volume of the liquid.
The density of water is known to be 1g/cm³.
Using the known weight of the water-filled bottle, we can calculate its volume:
Volume of water = (Bottle + water weight) - (Empty bottle weight)
Volume of water = 75g - 25g
Volume of water = 50 cm³
Step 3: Calculate the density of the liquid.
Density is calculated by dividing the mass of the liquid by its volume.
Density of the liquid = Mass of the liquid / Volume of the liquid
Density of the liquid = 40g / 50cm³
After performing the division, the density of the liquid is:
Density of the liquid = 0.8 g/cm³
So, the density of the liquid is 0.8 g/cm³.
Thx so much
Very good
Thanked you
