I could not find any answer to this question on the internet, either.
But if you look up for "density of wood" you will find that the density of Pine is between 450 and 600 kg/m3.
Douglas Fir Pine density (which is the type of wood we used in CA for structures) is 590 kg/m3
Let's use the metric system and then we will covert the result to our system.
So, let's start calculating the volume of a 2x12. Let's consider a plank with a length of 16 feet.
- 2x 12 is actually 1.5 inches x 11.5 inches, or 17.25 sq in or 116.6711 sq cm
- multiply it now by the length (16*12 inches or 488.64 cm) to obtain the volume:
57,010.16 cu cm (cm3)
- one cubic meter = 1,000,000 cubic centimeters
- so a 2x12x16 would weigh 590 * 57,010.16 / 1,000,000 = 33,63 kg or
approx 74 lbs
Hope this helps ...

How do you Convert 86.2 grams c small 2 hsmal 4 to moles?
Carbon (C) has a atomic weight of 12 gr/mol Hydrogen (H) has an atomic weight of 1 gr/mol Therefore C2H4 has a molecular weight of 28 gr/mol (2x12 + 4x1) By dividing 86.2 grams by 28 gr/mol, you get 3.59 moles.
