Chemistry Lesson

Here's an equation that I don't remember from Dr. Covey's Chemistry class at UConn:

((0.75) Ar + (0.25) CO2) x (60 liter^3) = $79.25

Also, I guess it's been a long time since I've had to refill a bottle of gas for the MIG welder...

YIKES!

I just filled a 4' bottle of Argon and I swear it was only $20.

Yeah, last time I filled our 40 (also 75/25 mix) it was $26.

Granted, there may have been issues in the industry since then, like when acetylene spiked a while ago.

it's because your bottle is liters cubed. if it was just liters, your price would've been the cube root of $79, or about $4.29.

Yeah, it's getting expensive to weld stuff....I got sticker shock last time I filled my gas bottle, and I refill mine about once or twice a year so it's not like it's been a decade. Thank goodness I don't have to count it towards my $20xx budget!

I really don't understand why the price rose so quick, recently. Is argon a hot commodity or something...???

Is a 4ft acetylene bottle exchange still $100?

WTF is a cubic liter? Liters are volume already.

Metric gases are so darned expensive ...

That's why it was so expensive. It's cubed, so 60x60x60 is 216,000 Liters. At $79, he's actually getting a pretty good deal.

I like cubed ice and cubed ham ... but with argon, wouldn't the pointy corners get stuck in the hose?

don;t be such a square

I asked if they sold it by weight or volume and they said volume. It was not a four foot bottle.

You know that's not a real equation, right?
