Molarity = moles of solute/volume of solution
0.324 M H2SO4 = moles H2SO4/500 ml
162 millimoles, or, more precisely to the question
0.162 moles H2SO4
The mole fraction must be calculated in moles solvent over moles solution. So, 3.4 grams sulfuric acid equals .0347 moles sulfuric acid. 3500 mL water equals 3500 g water equals 194 mols. .0347 mols/(.0347+194) = 1/5591.77 mols/mol
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
4. The chemical equation is Cu + H2SO4 → CuSO4 + H2. Copper and sulfuric acid have the same coefficient (1), so the same number of moles of copper and sulfuric acid are used.
No, a sulfuric acid solution in water is homogeneous

1 mole sulfuric acid for 1 mole calcium chloride
No, a sulfuric acid solution in water is homogeneous
Sulfuric acid is a compound.
In the acid-base reaction where sodium hydroxide and sulfuric acid react, the formula is: H2SO4 + 2NaOH --> Na2SO4 + 2H2O. The coefficients shown are necessary to uphold the law of conservation of mass. So, if you have 17 moles of sulfuric acid, you will need twice as many moles of sodium hydroxide, so the answer is 34 moles NaOH.
The molecular formula for sulfuric acid is H2SO4. This shows that each molecule contains exactly 4 oxygen atoms. Therefore, 0.750/4 or 0.1875 moles of sulfuric acid contain 0.750 moles of oxygen atoms.
Sulfuric acid is not obtained from water.
The normality of a solution is the gram equivalent weight of a solute per liter of solution. For example, 1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles H+ ions.
