5liters of alcohol has a mass of 4kg.the density of alcohol?
Density(volumetric mass density) =mass/volume
Density = 4kg/5Liters = 0.80 kg/Liter.
Liter = .1^3 m^3 = .001 m^3
so
.8*1000 = 800 kg/m^3
which is 80% density of water
To find the density of alcohol, you need to divide the mass of alcohol by its volume. The formula for density is:
Density = Mass / Volume
Given:
Mass = 4 kg
Volume = 5 liters
Now, let's calculate the density:
Density = 4 kg / 5 liters
First, we need to convert liters to cubic meters because the SI unit for volume is cubic meters.
1 liter = 0.001 cubic meters
So, we have:
Volume = 5 liters * 0.001 cubic meters/liter
Volume = 0.005 cubic meters
Now, we can calculate density:
Density = 4 kg / 0.005 cubic meters
Density = 800 kg/cubic meter
Therefore, the density of alcohol is 800 kg/m^3.
