1. The problem statement, all variables and given/known data Deoxyribonucleic acid (DNA) is thought to be the chemical compound responsible for the process of heredity. A sample of DNA was found to have density 1.10 g/cm3 and its molecular weight was estimated to be 3.04 × 108 g. What is the average volume occupied by one DNA molecule? 2. Relevant equations 3. The attempt at a solution I am stuck here. I know V = mass/density Would I go something like: 3.04 x 10^8 g per mol x (1 mol / 6.022x10^23 molecules) x ( 1 cm^3 / 1.10 g) No thats not right...dammit Any help would be great. I know its a simple question, but I need to know exactly how to get the answer. Thanks all!!!
