The "air" in the space suit of astronauts is actually pure oxygen supplied at a pressure of 0.30 bar. the two tanks on a space suit each have a volume of 3980. cm3 and have an initial pressure of 5860. kpa. assuming a tank temperature of 16 c, what mass of oxygen is contained in the two tanks?

Answer asap need 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.
