Indicate what the researcher did incorrectly in this procedure. A researcher wanted to make 1 L of a 2M sucrose solution. They calculated that 2 moles of sucrose (342 g per mole) weighs 684 grams. They carefully measured 1 L of water and poured it into a beaker (2 L capacity), added a stir bar, and placed the beaker on a magnetic stir plate. They then gradually added the 684 g of sucrose to the beaker and waited for it to dissolve.

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
