Question

A special flask used in the determination of densities called a pyconometer, has a mass of 16.3179g. when empty, and it has a mass of 48.0250g when filled with water at 20 degrees Celsius. When this same pyconometer is filled with ethyl alcohol at 20 degrees Celsius, it is found to have a mass of 41.3934g. Find the density of ethyl alcohol at 20 degrees Celsius?

Answer 1

$\rho=\frac{41.3934-16.3179}{48.0250-16.3179}=0.79084$
