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.
