Solution Steps

Step 1: Identify the benefits of grounding the secondary

Grounding the secondary of a transformer or electrical system can provide several benefits. These benefits typically include:

  1. Safety by providing a path to ground for fault currents.
  2. Stabilization of voltage levels within the system.
  3. Reduction of common-mode noise, which can interfere with sensitive electronic equipment.
Step 2: Evaluate the given options
  • Voltage increase: Grounding the secondary does not typically result in a voltage increase. Instead, it helps stabilize the voltage.
  • Resistance decrease: Grounding the secondary does not directly affect the resistance of the system.
  • Common-mode noise reduction: Grounding the secondary can help reduce common-mode noise by providing a reference point and a path for noise currents to dissipate.
Step 3: Select the correct answer

Based on the evaluation, the correct benefit of grounding the secondary is the reduction of common-mode noise.

Final Answer

\(\boxed{\text{common-mode noise reduction}}\)

An analytical chemist weighs out 0.165 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with 0.0600 M NaOH solution. When the titration reaches the equivalence point, the chemist finds he has added 41.0 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.
