Answer:

A buffer solution is prepared by adding 13.74 g of sodium acetate (NaC2H3O2) and 15.36 g of acetic acid to enough water to make 500 mL of solution.

Calculate the pH of this buffer.

Explanation:

The pH of a buffer solution can be calculated by using the Henderson-Hesselbalch equation:

pH=pKa+log\frac{[salt]}{[acid]}

The pH of the given buffer solution can be calculated as shown below:

What is the molarity of a solution that contains 5.0 moles of solute in 2.0 liters of solution? 1.0 M 2.5 M 1.5 M 0.4 M
icang [17]
The molarity of a solution is defined as the moles of solute over liters of solution. That means that M=5/2=2.5. Therefore the answer is 2.5M. I hope this helps. Let me know if anything is unclear.
