we have a 25 milliliters mark on a flask that's filled all the way up with ethyl alcohol. Therefore, we know that the volume of this alcohol is going to be 25 milliliters. We also know that by measuring the massive, it's the massive. It's is, in fact, 19.73 to 5 grams. We can use that first to find the density. Density is mass over volume, so in this case it would be 19.732 grams for every 25 ...
