what is the gram molecular mass of the compound with the formula CH3COOH ?
(1)22.4 g
(2)44.0 g
(3)48.0 g
(4)60.0 g
You look up the atomic masses on the periodic table and add them. CH3COOH is abour 60.
To determine the gram molecular mass of a compound, you need to calculate the sum of the atomic masses of all the elements in the compound.
In this case, the compound has the formula CH3COOH, which consists of carbon (C), hydrogen (H), and oxygen (O).
To find the atomic masses of these elements, you can consult the periodic table. The atomic mass of carbon is approximately 12.01 g/mol, hydrogen is approximately 1.01 g/mol, and oxygen is around 16.00 g/mol.
Now, let's calculate the gram molecular mass:
1 carbon atom (C) = 12.01 g/mol
3 hydrogen atoms (H) = 3 x 1.01 g/mol
2 oxygen atoms (O) = 2 x 16.00 g/mol
Total = (12.01 g/mol) + (3 x 1.01 g/mol) + (2 x 16.00 g/mol) = 12.01 g/mol + 3.03 g/mol + 32.00 g/mol = 47.04 g/mol
Therefore, the gram molecular mass of CH3COOH is approximately 47.04 g/mol.
None of the presented answer choices match the calculated result of 47.04 g/mol.
