Q
Q: How many grams are in 0.25 moles of sulfuric acid (H2SO4)?
Solution:
Molar mass of H2SO4 = 98 g/mol. Mass = moles x molar mass = 0.25 moles x 98 g/mol = 24.5 g.
Steps: 7
Show Steps
Step 1: Identify the chemical formula of sulfuric acid, which is H2SO4.
Step 2: Calculate the molar mass of H2SO4 by adding the atomic masses of its elements: 2 hydrogen (H), 1 sulfur (S), and 4 oxygen (O).
Step 3: The atomic mass of hydrogen is approximately 1 g/mol, sulfur is approximately 32 g/mol, and oxygen is approximately 16 g/mol.
Step 4: Calculate the total molar mass: (2 x 1) + (1 x 32) + (4 x 16) = 2 + 32 + 64 = 98 g/mol.
Step 5: Use the formula to find mass: Mass = moles x molar mass.
Step 6: Substitute the values: Mass = 0.25 moles x 98 g/mol.
Step 7: Calculate the mass: 0.25 x 98 = 24.5 g.
