A bungee jumper (m = 66.00 kg) tied to a 39.00 m cord, leaps off a 69.00 m tall bridge. He falls to 5.00 m above the water before the bungee cord pulls him back up. What size impulse is exerted on the bungee jumper while the cord stretches?

**Ap Chemistry**

The mass of the sample was .0258 grams. then I divide that by 50 ml, multiple by 250 ml bleach sol'n, divide by 5 ml bleach, and divide by density of bleach (.5894). And then I get .0438 grams of ClO. Then I divide .0258 grams and .0438 and get .589, and multiple by 100 to...

The mass of bleach? Well, 5 ml was 2.947 grams, but I need the amount per 50 ml sample to do a stoichiometry equation.

I'm doing the calculations on the lab "Oxidizing Power of Laundry Bleach," and I'm stuck on one part. This is what I have so far: My average volume of sodium thiosulfate is 6.94 ML. I then converted that into moles and got 6.94X10^-4 moles. That means that Na...
