Step 2: Calculate the mass of H₂SO₄ requiredNext, we need to convert moles of H₂SO₄ to grams using its molar mass. The molar mass of H₂SO₄ is approximately 98 g/mol.Mass of H₂SO₄=Moles×Molar massCalculating the mass:Mass of H₂SO₄=0.2mol×98g/mol=19.6...
The units of molality are moles per kilogram. The difference between molality and molarity is that molarity is measured in volume per liter of the solution.Answer and Explanation: the mass of 6.0 moles of H2SO4 is 6×(2×1+32+4×16)=6×98=588g if the solutio...
Step 4: Calculate the molarity of the H₂SO₄ solutionNow we can calculate the molarity (M) of the H₂SO₄ solution using the formula: Molarity (M)=Number of molesVolume in liters First, convert the volume from mL to L: Volume in liters=55.56 mL×1 L1000 mL=0.05556 L Now,...
