Convert 89.44g to kilograms. Write answer in scientific notation (no label needed) and to two
decimal places. (1x10^11 5 = 15. 1000g = 1kg)
When typing in scientific notation into the answer field use a lower case "x" and (shift ó for PC).
For example, 1.00x105 is written as 1.00x1045 and 1.00x10-5 is written as 1.00x10^-5 (NO SPACES
BETWEEN ANY NUMBER OR FUNCTION!).

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.
