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`

A cylindrical solid of mass 10^(-2) kg and cross-sectional area 10^(-4) m^(2) is moving parallel to its axis (the x-axis ) with a uniform speed of 10^(3) m//s in the positive direction. At t = 0 , its front face passes the plane x = 0 . The region to the right of htis plane is filled with the dust particle of uniform density 10^(-3) kg/m^(3) . When a dust particles collides with the face of the cylinder, it stricks to its surface.
