Answer 2

It seems there might be some confusion in the chemical formulas you've provided. Let's correct them and calculate the molar masses:

1. HCl (Hydrochloric acid):

   • Hydrogen (H) has a molar mass of approximately 1.007 g/mol.
   • Chlorine (Cl) has a molar mass of approximately 35.453 g/mol.

   The molar mass of HCl = 1.007 g/mol + 35.453 g/mol ≈ 36.460 g/mol.

2. NH3 (Ammonia):

   • Nitrogen (N) has a molar mass of approximately 14.007 g/mol.
   • Hydrogen (H) has a molar mass of approximately 1.007 g/mol.

   The molar mass of NH3 = 14.007 g/mol + (3 * 1.007 g/mol) ≈ 17.031 g/mol.

3. HCOOH (Formic acid):

   • Hydrogen (H) has a molar mass of approximately 1.007 g/mol.
   • Carbon (C) has a molar mass of approximately 12.011 g/mol.
   • Oxygen (O) has a molar mass of approximately 15.999 g/mol.

   The molar mass of HCOOH = 1.007 g/mol + 12.011 g/mol + 2 * 15.999 g/mol ≈ 46.025 g/mol.

4. Al(OH)3 (Aluminum hydroxide):

   • Aluminum (Al) has a molar mass of approximately 26.982 g/mol.
   • Hydrogen (H) has a molar mass of approximately 1.007 g/mol.
   • Oxygen (O) has a molar mass of approximately 15.999 g/mol.

   The molar mass of Al(OH)3 = 26.982 g/mol + 3 * (1.007 g/mol + 15.999 g/mol) ≈ 78.003 g/mol.

5. CaCO3 (Calcium carbonate):

   • Calcium (Ca) has a molar mass of approximately 40.078 g/mol.
   • Carbon (C) has a molar mass of approximately 12.011 g/mol.
   • Oxygen (O) has a molar mass of approximately 15.999 g/mol.

   The molar mass of CaCO3 = 40.078 g/mol + 12.011 g/mol + 3 * 15.999 g/mol ≈ 100.086 g/mol.

Please note that these molar masses are calculated based on the atomic masses of the individual elements and may vary slightly depending on the isotopic composition of the elements.
