How many grams of acetic acid (C₂H₄O₂)would you use to make 10 L of a 0.1 M aqueous solution of acetic acid? (Note: The atomic masses, in daltons, are approximately 12 for carbon, 1 for hydrogen, and 16 for oxygen.)

Question

The molar mass of acetic acid (C₂H₄O₂) is calculated as follows:

2(12.01 g/mol) + 4(1.01 g/mol) + 2(16.00 g/mol) = 60.05 g/mol

To make 10 L of a 0.1 M solution of acetic acid, we need:

0.1 mol/L × 10 L = 1 mol of acetic acid

Therefore, we need 1 mol × 60.05 g/mol = 60.05 g of acetic acid to make 10 L of a 0.1 M solution of acetic acid. The closest answer choice is D) 60 g.
