For this case we have:
[tex]10 ^ {- 20}[/tex], we must run the decimal point 20 spaces to the left.
[tex]0.00000000000000000010 \ kg[/tex]
[tex]10 ^ {- 12}[/tex], we must run the decimal point 12 spaces to the left.
[tex]0.000000000010 \ kg[/tex]
Thus, it is observed that the mass of a small virus is smaller!
We subtract and obtain:
[tex]10 ^ {-11}[/tex]
ANswer:
The mass of a small virus is less!
