A plant virus is found to consist of uniform cylindrical particle of `150 Å` in diameter 5000 Å long. The specific volume of the virus is 0.75 `mLg^(-1)`. If the virus is considered to be a single particle, find its molar mass.

Text Solution

Verified by Experts

The correct Answer is:
`7.09 xx 10^(7)`
`M=pixx(75xx10^(-8)cm)^(2)xx(5000xx10^(-8)cm)`
`xx(1)/(0.75cm^(3)//gm)xx6.023xx10^(23)=7.09xx10^(7)gm`
