How much does a cubic foot of nitrogen weigh?

Lithium is a bit more than half as dense as water. Its relative density -- or, if you prefer, specific gravity -- is 0.53. So, if you know how much a cubic foot of water weighs, multiply that value by 0.53. BTW, one gallon of water (at 4 degrees C) weighs 8.34 pounds, and one cubic foot of water contains 7.48 gallons. (I know that because WikiAnswers told me.) Now you've got all the info you need to make the calculation.

Explain why density is a size independent property?

Units of density are mass per unit volume. Unit volume might be a cubic centimeter or a cubic foot, for example. Whatever the size of your sample, a cubic foot of it is always a cubic foot, and the mass of that cubic foot will always be the same.
