a normal 2X4 weights between 8 to 10 pounds
Yes
Answer By putting your ear to the wall : A wall is a collection of studs (usually sized 2x4 or 2x6) equally spaced (usually 16 in. or 24 in. on center) and sandwiched between top and bottom plates. : If you start from the corner, you can measure 16" or 24" and hope that you find a stud. You can hit the wall, and where it sounds more hallow, no stud exists where the sound is higher, there is a stud. But if you can't tell a difference, then measuring could be your only bet.
They hold very well, better than into wood.
5-6" The average wall is a constructed 2x4 stud wall with a layer of Sheetrock on top of that. As can be found on the Internet, a 2x4 is actually 1.5" x 3.5" And a piece of Sheetrock is .75" So .75+.75+3.5= 5" An exterior wall is thicker due to the different materials used in the construction. It is also has a 2x4 stud wall framing with a layer of 3/4" OSB(Oriented Strand Board) or Plywood with a layer of plastic (negligible thickness) and the exterior material on top of that. Other Variations include various foams and insulation layers.

A 2X4 would be a stud, not a board. Weight depends on the length and species, if it is pressure treated or not. 8ft. hem-fir 2X4 is about 8 pounds or so.
About 10 pounds.
2x4's have a weight that varies based upon wood and length. With this said, the weight generally runs at about one point twenty-eight pounds per foot in length. Thus, an eight foot 2x4 would run about eleven pounds.
No
Yes, wood floats.
A 2x4 is simply a piece of wood- ANY wood- that is 1 1⁄2 inches by 3 1⁄2 inches. They are commonly made from pine, fir or spruce, but COULD be any wood.
It varies. Is it yellow pine,spruce,and wet or dry ? A 2X4 Spruce/ Pine/ Fir KD 1.375 lbs per foot ( Used for interior building in projects New England ) 2x4 Pressure Treated southern yellow Pine 2.175 lbs per foot. (Used for exterior building projects ie. Deck railings) That actual weight will vary depending on exactly which species, and how dry / wet the wood is. But these are generally excepted weights we use in calculating shipping weight for these types of wood.
You will need at least 13-9' 2x4's, on 16" centers, and 2-16' 2x4's for plates. (Deduct plate thickness from stud length)
The color identifies them as "stud grade" pine.
1 and a half inches by 3 and a half inches. Note that an "8 foot 2x4" is 8x12" = 96" long, but a "2x4 stud" is 92 5/8" long to allow for bottom and top plates to make wall framing go quicker.
