2Al + 6HCl → 2AlCl3 + 3H2 If 3.0 grams of H2 were produced, how many grams of Al reacted? (Molar mass of Al = 27 g/mol, molar mass of H2 = 2.0 g/mol) ___ grams

Answer:

its actually 26.8 rounded to three sig figs

Explanation:

ur welcome

The 2AI + 6HCL = 2ALCL3 + 3H2. of the 3.0 gms of H2 are made.

  • The values derived from the grams of H2 in production can be used for finding the molar mass of AI of 27.
  • AI will react and make a 26.8 g of AI as molar mass consists of AI = 27 g / ml and the M of the H2 = 2.0g/ mol gms.
  • The calculated M of grams is 26.8 rounded to 3g figures.
