A metal is reacted with HCl to produce hydrogen gas. If 0.0623 gram of metal produces 28.3 mL of hydrogen at STP, the mass of the metal that reacts with one mole of hydrochloric acid is Correct Answer 24.7 g

(C) We set up the problem with the desired ratio to the left of the equal sign. To the right of the equal sign replace the given mass of metal in the numerator and the volume of H2 in mL in the denominator. Since we already know the value of the final numerator, we just need to convert the denominator into moles of HCl.
