To calculate the requested values, we'll need to use the given information and apply the appropriate formulas. Here's how you can calculate each value:

(A) Mass % H2SO4 (m/m):

Mass % H2SO4 (m/m) is the ratio of the mass of H2SO4 to the total mass of the solution expressed as a percentage.

1. Calculate the mass of the H2SO4 in the solution:
Mass of H2SO4 = 200.1 g

2. Calculate the total mass of the solution:
Total mass of the solution = density × volume
Total mass of the solution = 1.3294 g/ml × 0.3500 L × 1000 ml/L

3. Calculate Mass % H2SO4 (m/m):
Mass % H2SO4 (m/m) = (Mass of H2SO4 / Total mass of solution) × 100

(B) Mass % H2O (m/m):

Mass % H2O (m/m) is the ratio of the mass of water (H2O) to the total mass of the solution expressed as a percentage.

1. Calculate the mass of water:
Mass of water = Total mass of the solution - Mass of H2SO4

2. Calculate Mass % H2O (m/m):
Mass % H2O (m/m) = (Mass of water / Total mass of solution) × 100

(C) Molarity:

Molarity is defined as the number of moles of solute per liter of solution.

1. Calculate the number of moles of H2SO4:
Moles of H2SO4 = Mass of H2SO4 / Molar mass of H2SO4

2. Calculate Molarity:
Molarity = Moles of H2SO4 / Volume of solution

(D) Molality:

Molality is defined as the number of moles of solute per kilogram of solvent.

1. Calculate the mass of water in kilograms:
Mass of water in kg = Mass of water / 1000

2. Calculate Molality:
Molality = Moles of H2SO4 / Mass of water in kg

Please note that to calculate the molar mass of H2SO4, you will need to refer to the atomic masses of the elements involved (H = 1.0079 g/mol, S = 32.06 g/mol, O = 15.999 g/mol).

By applying these formulas, you can find the answers to all four parts of the question.
