We have a fusion of metals A and B, their molar ratio is 1:1. If we pour 1.02 grams of this fusion into excess HCl solution, we will get 1120 mL of hydrogen gas. We would get the same amount of hydrogen gas if we poured 1.7 grams of our fusion into excess NaOH solution. What is the composition of this fusion?
