When considering atomic orbitals the only important information they really wanted to know is the size of the orbit, which was described by using quantum numbers.
As the question tells you, you need to use the formula
% mass= mass of solute/ mass of solution x 100
mass solute= 30.0 g
mass of solution= 30.0 + 270.0= 300.0 g
% mass= 30.0/ 300.0 x 100= 10%
answer is B
I couldn't really find anything about the growth time but it does say that it could remain viable in soil for up to 40 years
