Question: What is the equivalent weight of H2SO4 if its molar mass is 98 g/mol?

Options:

Correct Answer: 49 g

Solution:

Equivalent weight = molar mass / number of equivalents = 98 g/mol / 2 = 49 g.

What is the equivalent weight of H2SO4 if its molar mass is 98 g/mol?

What is the equivalent weight of H2SO4 if its molar mass is 98 g/mol?

Step 1: Identify the molar mass of H2SO4, which is given as 98 g/mol.
Step 2: Determine the number of equivalents for H2SO4. Since it can donate 2 protons (H+ ions), the number of equivalents is 2.
Step 3: Use the formula for equivalent weight: Equivalent weight = molar mass / number of equivalents.
Step 4: Substitute the values into the formula: Equivalent weight = 98 g/mol / 2.
Step 5: Calculate the equivalent weight: 98 g/mol divided by 2 equals 49 g.
