A piece of metallic iron (10 moles) was dissolved in concentrated hydrochloric acid. The reaction formed hydrogen gas and iron chloride. How many grams of HCl were consumed? Don't forget the units. Fe+2HCl---->FeCl2+H2

asked by Meladee
  1. 1. You have the balanced equation.
    2. You know you start with 10 moles Fe.
    3. Using the coefficients in the balanced equation, convert moles Fe to moles HCl.
    4. Now convert moles HCl to grams. g = moles x molar mass.
