Question- Assume that a 2.130 g sample of bleach was weighed out as outlined in the procedure. When a sodium thiosulfate solution containing 6.829g of Na2S2O3 x 5H2O in 250.0ml was used to titrate the above bleach sample, it required 11.21ml to reach the strach endpoint.

What was the molarity of the sodium thiosulfate pentahyrdate solution?

What is the number of moles of Na2S2O3 in the 11.21 ml?

What is the number of moles of I2 that react with the Na2S2O3?

How many moles of NaOCl are in the bleach sample? How many grams?

What is the percent by mass of NaOCl in the blach?

You must show your work in an efficient manner so I can understand it in clearly
