find the density of ethyl alcohol if 80.0 cm^3 "weighs" 63.3g.
To find the density of ethyl alcohol, you need to use the formula:
Density = Mass / Volume
In this case, the mass is given as 63.3 grams and the volume is 80.0 cm^3.
So, you can divide the mass by the volume to calculate the density:
Density = 63.3 g / 80.0 cm^3
To simplify the units, you can convert cm^3 to mL because they are equivalent:
Density = 63.3 g / 80.0 mL
Finally, divide the mass by the volume to get the density:
Density = 0.791 g/mL
Therefore, the density of ethyl alcohol is 0.791 g/mL.
