# Answer to Question #56041 in Cell Biology for Misha Jain

Question #56041

If the length of DNA is 1.36 mm, the number of base pair and nucleosomes in it will be?

Expert's answer

Answer

36.9 L

Solution

PV = nRT

V = nRT / P

Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)

n(H2) = n (Mg) = m (Mg) / M (Mg) = 41.0 g / (24.0 g/mol) = 1.7 mol

R = 62360 mmHg/mol*K

T = 23 ˚C + 273 = 296 K

V(H2) = (1.7 mol * 62360 mmHg / mol*K * 296) / 850 mm Hg = 36917.1 ml = 36.9 L
