A standard pencil lead typically weighs about 0.1 gram.
On average, a standard pencil lead weighs about 0.2 grams. The weight can vary slightly depending on the type and size of the pencil lead.
It can draw a line about 35 miles.
A standard pencil contains about 0.4-0.5 grams of graphite, not lead. The term "lead" dates back to the Roman times when writing instruments were made using lead, but modern pencils use graphite.
The main body of the pencil is made from soft wood which is naturally boyant, the pencil 'lead' is not lead at all but a much lighter substance called graphite. Your pencil is just not heavy enough to sink.
Water it depends how much water and many pencils. etc

None. It is graphite not lead in a pencil. How much graphite in a pencil? About 2/3 cubic inch (=6" x pi * (3/16)^2)

Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
For the same reason a pen is not a pencil. Mass = weight Volume = how much space it takes up. Ask yourself this question. What weighs more, a pound of lead, or a pound of feathers? Imagine it in your head, what each would look like and that gives you the answer.
3 grams.
Its the mass that measures the matter in an object
Your pencil lead may be breaking because you are applying too much pressure while writing or drawing. Try using a lighter touch to prevent the lead from breaking. Additionally, make sure your pencil is sharp and not worn down, as a dull tip can also cause lead breakage.
Mass measures the amount of matter in a sample.
0.5 lead may or may not be equivalent to a #2 pencil. #2 refers to the hardness of the lead, while numbers referring to mechanical pencil leads such as 0.5mm and 0.7mm refer to the width of the lead. 0.5mm lead will be finer and likely more prone to breaking, but can allow much finer lines to be drawn. 0.7mm lead will usually be slightly more resistant to breakage, but will have thicker lines.
