Agas can holds 2.0 gal of gasoline. what is this quantity in cubic centimeters?

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
