Question

One molecule of the antibiotic penicillin G has a mass of ______. What is the molar mass of penicillin G?

Answer 1

The molar mass of penicillin G is 334.43 g/mol.

Step-by-step explanation:

The molar mass of penicillin G can be calculated by adding up the atomic masses of all the atoms in one molecule of penicillin G. The molecular formula of penicillin G is C16H18N2O4S. Using the atomic masses from the periodic table, the molar mass can be calculated as follows:

1. Molar mass of carbon (C) = 12.01 g/mol
2. Molar mass of hydrogen (H) = 1.008 g/mol
3. Molar mass of nitrogen (N) = 14.01 g/mol
4. Molar mass of oxygen (O) = 16.00 g/mol
5. Molar mass of sulfur (S) = 32.07 g/mol

Using the molecular formula, we can calculate the molar mass as:

Molar mass of penicillin G = (16 × 12.01) + (18 × 1.008) + (2 × 14.01) + (4 × 16.00) + (1 × 32.07) = 334.43 g/mol

Therefore, the molar mass of penicillin G is 334.43 g/mol.
