An empty density bottle has a mass of 15 g when full of alcohol of density 0.8 g per centimeter cubic it's mass is 47 g calculate its mass when full of water
To find the mass of the density bottle when full of water, we need to subtract the mass of the empty density bottle from the combined mass of the alcohol and the density bottle when full.
The mass of the empty density bottle is 15 g.
The mass of the alcohol plus the density bottle when full is 47 g.
Therefore, the mass of the alcohol is 47 g - 15 g = 32 g.
The density of water is 1 g/cm³.
Since the density of the alcohol is 0.8 g/cm³, the density bottle is already partially filled when it is full of alcohol.
To find the mass of the density bottle when full of water, we need to subtract the mass of the alcohol from the combined mass of the alcohol and the density bottle when full.
The mass of the density bottle when full of water is 47 g - 32 g = 15 g.
Therefore, the mass of the density bottle when full of water is 15 g.
