A sheet of A4 paper weighs about 4.5 grams. Comic book paper is probably thinner and smaller, so let's say 3.5 grams. According to a 5 second google search, a comic has an average of 32 pages. 32 x 3.5 = 112 grams (the mass of a comic book). To get the weight: 0.112 kg x 9.8 = 1.1 N
An average comic book weighs about 1.1 N and has a mass of 112 g.
Not all comic books weigh the same, but the average comic book weighs about 1.5 ounces.
Most comics won't weigh the same. They can have different numbers of pages, can be different sizes and can even be printed on different types of paper. It all depends.
