1. The Human Body is said to contain approximately 50.0 grams of DNA in the entire body. If the number of nucleotides in one strand of DNA is approximately 3.0*10^6, and the average molar mass of a nucleotide is 327 g/mol, what is the average molar mass of an entire DNA double helix?

2. The total mass of DNA in the body is 50.0g. If the number of nucleotides in ONE STRAND of DNA is approximately 3.0*10^6, and the average length of a single nucleotide is 0.34 nm, what is the length (in km) of one strand of DNA when it is stretched out to its maximum length (not in a helix)?

3. If the average volume of all the blood in a human body is 4700 mL, what is the molarity of DNA in the human blood system?

Thanks!!
