That is about 2 egg whites
Hard boiled chicken egg, 100 grams = 1.1 grams of carbs
There are about 1.6 grams of carbs in four eggs.

Almost half
According to most sources a large egg white has between .3-.8g of carbs so a jumbo I would assume it between .6-1g. Ether way it is pretty low in carbs since these are not net carbs (bad carbs), which should be even lower.
Since every egg is slightly different in size, estimation is needed. One US Extra-Large egg (Large for UK) has about 40 grams of egg white. As such, 11 egg whites from eggs of this size will get around one pound of egg whites total.
The egg white of one large egg is around 30 to 40 grams. Therefore, you can get close to 35 grams of egg white out of one large egg. You may need to add a little egg white from a second egg to get the full 35 grams.
There is no carbs in egg White or indeed and part of the egg. (I don't know about the shell.)
