8oz jar of mercury what does it weigh?

Question

someone told me that it weighs 25 pounds

Answer 1

13.55g/ml      and  30ml/oz.

so it is 13.55x30x8=3252g

3.252kgx2.2lbs/kg  

so it is not 25 lbs

Answer 2

Density = 13.534 gm/ml

1 oz = 29.573 ml

1 pound  = 453.59 gm

13.534 gm/ml x 29.573 ml/oz x 8 oz = 3,201.9 gm/8 oz

3201.9 gm/453.59 gm/lb = 7.06 lbs.

Still much heavier than it looks.

Answer 3

Well subtract the weight of the jar from 8oz and you have your weight.

Answer 4

well Chemistry works in the metric system so we have to do some converting.

8 Fluid ounces = 0.24 Liters

and the weight of one mole of Mercury is 200.59 grams

I'll save you the calculations and tell you to go here...

http://www.allmeasures.com/Formulae/stat...

where you'll find the weight will be 3.2568000000000006 Kg

which = 7.180014952072801 pounds.

So 7.2 pounds is a lot, but NOT 25!!!
