find the density of ethyl alcohol if 80.0 cm^3 "weighs" 63.3g.
Good lord. "Weighs" is a silly term here.
density= mass/volume
To find the density of a substance, you need to divide its mass by its volume. In this case, the given information is that 80.0 cm^3 of ethyl alcohol weighs 63.3 g.
So, to find the density, you can use the formula:
Density = Mass / Volume
In this case, the mass is given as 63.3 g, and the volume is given as 80.0 cm^3.
Density = 63.3 g / 80.0 cm^3
To calculate this, you simply divide the mass by the volume:
Density = 0.79125 g/cm^3
The density of ethyl alcohol is approximately 0.79125 g/cm^3.
