15)An aqueous solution is 20.0% by mass of sodium thiosulfate pentahydrate, Na2S2O3•5H20. What is the molarity of Na2S2O3 in this solution at 20°C? The density of this solution at 20°C is 1.176 g/mL.
Molarity = mol/L

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
