The oxygen saturation of a lake is found by dividing the amount of dissolved oxygen the lake water currently hasper liter by the dissolved oxygen capacity per liter of the water, and then converting that number into a percent. if the lake currently has 7.4 milligrams of dissolved oxygen per liter of water and the dissolved oxygen capacityis 9.4 milligrams per liter, what is the oxygen saturation level of the lake, to the nearest percent?me with this one ; (

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
