What do scientists do after the reach conclusions from the results of their experiments?
They share the results of the experiment.
The info collected during an experiment is called?
The results.
To be a valid scientific experiment the results must be?
Repeatable
What is the concentration of Na2SO4 solution prepared by dissolving 5.35 g of Na2SO4 in sufficient water to give 330 ml of solution?
First.Get moles sodium sulfate.5.35 grams Na2SO4 (1 mole Na2SO4/142.05 grams)= 0.0377 moles Na2SO4-------------------------------------Second.Molarity = moles of solute/Liters of solution ( 330 mL = 0.33 Liters )Molarity = 0.0377 moles Na2SO4/0.33 Liters= 0.114 M Na2SO4=============

An experiment in which the results are repeatable....apex
When you sum up what is learned in an experiment what is it called?
The outcome of an experiment is a "conclusion", the interpretation of the results compared with the expected results and the goal of the experiment.
What is a disadvantage of an vitro experiment?
A disadvantage of a vitro experiment is that the results can be misleading.
Do your results have to match your hypothesis in an experiment?
The results of a science experiment do not have to match the original hypothesis. Indeed, the results collected in an experiment may be completely different to those that the scientist predicted.
