paper clips do not weigh much, perhaps a gram each, so 10 weigh about 10 grams, so you would use grams, not kilograms, since 1 kg = 1000 grams
One dollar is a form of currency not mass
6 liters of water weigh approximately 6000 grams. A penny weighs about 2.5 grams. So, to find how many pennies have the same mass as 6 liters of water, you would divide 6000 grams by 2.5 grams per penny, which is 2400 pennies.

A kilogram is a measure of mass, not of weight.
The mass of a penny is approximately 2.5 grams. To make 5 grams, you would need 2 pennies, as 2.5 grams x 2 = 5 grams.
A zinc penny has a lower mass compared to a copper penny. This is because zinc is less dense than copper, so a zinc penny is lighter than a copper penny of the same size.
A British 1p coin has a mass of 3.56 grams, so 1 pound (currency) worth of pennies (that is, 100 of them) would have a mass of 356 grams. At normal Earth surface gravity this would correspond to a weight of roughly 3.49 N, or 12.6 ounces.If you meant "how much does a pound (weight) of pennies weigh", then I'm sorry, if you don't know that a pound of pennies, or anything else, weighs a pound then I don't think we can help you.
On Earth, 453.593 grams of mass (rounded) weigh one pound.
No, a new penny and an old penny have the same mass (2.5 grams). The difference in appearance is due to wear and tear on the surface of the coin rather than a change in mass.
Mass is measured in grams, not weight.
