Very nice Del. I did put a little thought into it but not to the degree you did. I was trying to anticipate void spaces but that truly is a WAG since gradation in not known or consistent. I guessed that with the void spaces removed you would end up with about 10 fluid oz. or 295.73 cubic centimeters x 19.3gm per cubic centimeter = 5707.59gm or 15.29 troy pounds. At least we did not start thinking about purity.
