3.9 What would be the saturation concentration (mole/L) of oxygen (O2) in a river in winter when the air temperature is 0 C if the Henry’s law constant at this temperature is 2:28 10␣3 mole=L-atm? What would the answer be in units of mg/L?

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 4.20 mol fe and 6.70 mol nio(oh) react?
