Question

A plant virus is found to consist of uniform cylindrical particles of 150 Armstrong in diameter and 5000 Armstrong long. the
specific volume of the virus is 0.75 cm3/g. If the virus is considered to be a single particle, find molar mass
A) 7.095 * 10^7 B) 70.95 * 10^7 C) 9.705 * 10^7 D) 7.095 *10^5
Pls give relevant answers step by step
