# The molecular weight of a virus!!

Chemistry Level pending

A plant virus is found to consist of uniform cylindrical particles of 150 angstrom in diameter and 5000 angstrom long. The specific volume of the virus is 0.75 mL/g. If the virus is considered to be a single particle, then it's molecular weight can be expressed in the form $x * 10^{7}$. Find x.

(The original question is taken from 1993 IIT JEE question paper.)
