How many moles of sodium hydroxide would have to be added to 150 mL of a 0.483 M acetic acid solution, in order to prepare a buffer with a pH of 4.480

0.068 moles of sodium hydroxide would have to be added to 150 mL of a 0.483 M acetic acid solution

Explanation:

As we know  

pH = pKa + log [salt]/[acid]

4.480= 4.74 + log [salt]/[acid]

log [salt]/[]acid] = -0.06

[salt]/[acid] = 0.87

moles acid = 0.150 L x 0.483 mol/L = 0.07245 moles acid

x/0.07245-x = 0.87

X- 0.07245 X = 0.87 *0.07245

X = 0.068 moles

i dont know

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
