I have always wondered this, but here it goes.

 

If I have a 15 pack of Kokanee beer rated at 5%/vol (which its stated on the can in front of me) and the can is 355ml then how much alcohol is in the can?

 

If I take that 355ml of beer rated at 5% and pour it into a large jug, then I add a shot say 25ml of 80 proof vodka. What is the rated alcohol content of that volume?

355*0.05=17.75, that's the amount of alcohol in one beer.

80 proof is 40%, so 25x0.4=10

So overall there is 27.75ml of alcohol in the new drink.

To work out the percentage, it's vAlc/vTotal x100

So 27.75/(355+15)x100

Which is 7.5% v/v

Makes sense. Can't hold stuff if you don't know what it is.

Well, my dergree is computational chemistry, this year i'm doing a master's and next i'm doing a PGCE which is a postgrad degree to become a teacher.

A couple of years ago I worked as a software analyst, basically earning £22k to do boring analysis of compounds myself and with other companies' equipment to compare the test results compared to our own equipment. The company I worked for made mass spectrometers, NMR machines and CHNS analysis machines. I was the lowest paid person at the office, it sucked. Becoming a teacher will be a pay cut again but hopefully I'll enjoy it more.

Computational chemistry sounds super interesting to be honest. Recenelty heard of GPU accelerated dft simulations. Shame that your first job didn't grant you any satisfaction. Routine analysis like that must be dull, did you work on the machines too, or were just designated to the analysis? 

Yeah teaching seems more and more interesting, good lecturers really do inspire.

It was both lab and equipment based.

Things like finding the purity of compounds which is more accurate with titrations whilst it's quicker on machines. Instruments usually only measure to 2 d.p which is ridiculously inaccurate, with classical analysis you can get down to 5 d.p and doing analysis on the differing results of the instruments was basically 6 months of my life that i'll never get back.

Then there was a bunch of stuff with the software. The people in IT must have been completely inept or something, they just couldn't get the software to draw graphs properly, the software just looked awful, like something out of the mid 2000s. It wasn't even that functional and you needed stuff like a ChemDraw license to use it. By default it would switch to ChemDraw once it had finished a GC-MS analysis that it thought had identified an organic or organometallic compound and to turn it off you needed to have a specific plugin. The software is finished now and I'm glad to say that it looks better and this was sorted but still... Talking to the boss was like picking teeth because he had his way of doing things; this guy wasn't a visionary, he was just a 40-year-old dude from County Derry who wears shorts in his time off work. Moron.

So you actually did three way tests? Direct, and on both your machines and the clients? Sounds like tedious work for sure... 

At college there are some ancient machines, but those are for students to work with, and not exactly important work. Never seen Chemdraw being used to display results alright. Well lesson learned I guess  and the industry isn't all rosy by the sounds of it.

Wow thanks.

 

I used to drink Vodka Coolers, started off with Mikes Hard, then Smirnoff coolers. Lots of sugar = bad hang overs.

Anway I remember walking into a casino at noon, sunny, +8C no snow on the ground. I was up and down all day.

I was drinking Smirnoff Coolers bottles at 7% then adding in a shot of vodka. I was hammered by the time I left at midnight.

Walking out the door swirling my keys in my hand, and security stops me. The only time any security has ever stopped me.

I  guess they to break the law.

Sorry, just realised a mistake in the final step of the calculation, used 15 ml rather than 25. Ah well, it's as near as makes no difference 7.5%

 

Yeah, I'm the same as you mate, I used to drink loads of ciders but then realised that I was drinking like 20+ g of sugar per pint. Now, I go for Diet or Zero Coke/Pepsi and vodka, so much better and less hangover, been experimenting with the less bitter G&Ts too. I am basically a menopausal woman at this point, the battle to end the hangover is real.

[yathis]

When I am in British Columbia I tend to drink those 2L plastic bottles of Cider.

When I go on a tear up, its ease into the beers, then go for the vodka. If I am roaming around I will buy a McDicks or Subway soda and go Orange or Rootbeer. I always love a strong tinge of vodka. When I was in Banff them piggies love to hang out in front of the McDicks, got pinched a few times, I got my spots there tho. Better to have a view and by water then concrete jungle.
