If you have 100 eggs, and you need 2 eggs and 100 g of flour to make a cake, how many cakes can you make using your eggs, and how much flour do you need?

100 g of flour is needed for a cake and each cake needs 2 eggs.
Since we ve 100 eggs it is possible to make 50 cakes and totally 5000 g of flour will be needed.

So if you have 200 portions of 50 ug in 10 mg, and each portion requires 200 ul, what volume of solution do you need to make up?

40ml. So if i dissolve 10mg in 40ml of saline, would it mean that 200ul of this solution will carry 50ug?
