Ametal stand specifies a maximum load of 450 lb. will it support an aquarium that weighs 59.5 lb and is filled with 37.9 l of seawater (d = 1.03 g/ml)?

First solve the mass of 37.9 L seawater

M = 37.9 L ( 1000 ml / 1L ) ( 1.03 g / ml)

M = 39037 g

Then convert it to lb

M = 39037 g ( 1 lb / 453.592 g)

M = 86.06 lb

Total weight = 86.06 lb + 59.5 lb = 145.56 lb so it can support the aquarium

To begin with, in general, most of the average plants will begin to sprout within 1-2 weeks given conditions, with some fruiting plants taking up to 3 weeks as well, it all depends!
