I only need answers for the highlighetd portions. This was a lab I performed in my chemistry, it was using vaccum filtration to collect solids from a Barium Chloride solution (BaCl2*2H2O). I took 0.780g of Barium Chloride. I added 25ml of water it at first, then transferred it to a 50ml flask and filled it to 50ml and completely mixed the solution. Then I took 38ml of Na3PO4 and mixed it with the 50ml BaCl2 solution into a 250ml beaker. After mixing those, I filtered it out and collected the solids.

A blood concentration of 0.065 M ethyl alchohol is sufficient to induce a coma. Blood alcohol content is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100mL of blood, so a BAC os 0.08 means your blood is 0.08% alcohol by volume. a) What is the total mass of alcohol (in grams) that it represents for the same adult male whose total blood volume is 5.6L? b) What percentage does it represent from the coma induced level?
