18) A galvanic cell has the following total chemical
reaction: 2H + (aq) + Mg (s) → H2 (g) + Mg2 + (aq). The
concentration of the electrolyte at the cathode is 1M while the
concentration of the electrolyte at the anode is 0.1 M. Calculate
the cell potential with standard temperature and pressure. Enter
the answer with two decimal places.
27) What is the bulk density of ammonia gas (NH3), in
grams / liter, when the temperature is 80 ° C and the pressure is
2.5 atm? Give the answer with two decimals. Do not use commas.
