How to Mix a 2mM solution of EtOH?
Q. Ok So I'm a little rusty on my chemistry, so here I am in bio lab wondering how to make a 2millimolar solution of EtOH and water. I'll take any help out there. Chris, you're awesome. Thanks!

A. you need 0.002 moles of ethanol in 1 L of water. 0.002 moles of ethanol is 0.002*molecular weight (24+5+17)=0.092g. density is 0.789 g/ml so you need 0.092/0.789=0.117 ml and add water to 1 L

A. I don't know what moron told you to use 50% EtOH, but that will never get 25mg into 10 ml! Use 100% (or close to like 95%) EtOH, then you will be able to get 50 mg into 10 ml!--then use half as much of this stock, get it! Also store this solution in a dark cold place the best being a -20 freezer.

A. doctors and nurses are smart people and probably already tested you without even knowing. so yes, they can write about it in reports. did you give a urine sample? or they could have simply done it by blood, that is, if they drew any blood. edit: did you have any test done before? When you have surgery, docs do blood and urine tests to see that you are safe for the surgery. It is possible you could have had tests done a week or so before. Or it's entirely possible that they f'ed up & got the wrong patient with your chart.

Q. Could someone please help me with this question? If the average person has 6 L of blood, how many moles of EtOH would their blood contain if they met the legal definition of intoxication?
Asked by Eliz n - Sat Feb 7 12:58:44 2009 - - 2 Answers - 0 Comments
A. In the UK the legal maximum limit for alcohol in the blood is 80 mg per 100 mL. In 6 litres of blood there will be 80 x (6000 / 100) mg of alcohol = 4800 mg = 4.8 g The formula for ethanol is C2H5OH. The molecular mass is (2 x 12) + (6 x 1) + (1 x 16) = 46 g/mol The number of moles of ethanol is 4.8 / 46 = 0.104 moles.

A. Yep 78C is right.. You mean when cooking in with food? - well, it's lower that water - so there will be NONE left in the final food when the finished food in actually cooked (unless it's tar-tar). Anything that will produce stream will boil out the ethanol first, so it will be gone in a flash, and don't worry too much about fire, there will be too much saturated water vapor in the air to cause a fire. The only remnants of the alcohol in alcohol based cooking remaining are the flavors of the liquor that were present in the original. The white wine barreled and woodsy zest - the musty red wine oak flavors - perhaps the rum flavored oak and molasses flavors.

A. The ethanol will not burn at all in the microwave, but it should evaporate quickly. I don't think you would want a fire of any sort in your microwave. But, I would think it is more likely to have some ethanol remaining in food coming out of the microwave oven than food cooked in a frying pan in which the ethanol can be combusted (burned).

Asked by Rain - Tue Oct 2 21:43:52 2007 - - 1 Answers - 0 Comments
A. Even with your rephrasing, I'm not sure what exactly you're asking, but I'll try to answer. Being drunk by definition means there's an abnormal neurologic exam. In suspected head trauma, this can be impossibly confusing. Drunks also don't respond to pain normally, making the physical exam much less reliable. For instance, with the liver laceration, the perception pain or response to palpation of the right upper abdominal quadrant may be blunted. For this reason, drunks require more testing and imaging than sober, alert people. If you're asking about the hepatic enzyme tests on a chemistry panel, they're neither sensitive nor specific, so they're hardly worth doing in suspected hepatic injury. If there's reason to suspect such an injury,… [cont.]

A. It is KOEt / EtOH / heat followed by H2 / Pt The first step (KOEt/EtOH/heat) eliminates the Br to form the double bond to give isopropylcyclohexene. The second step (H2/Pt) reduces the double bond to give your final produce. Hope this helps.
