Q
Q: What is the mass of 3 moles of sulfuric acid (H2SO4)?
Solution:
Molar mass of H2SO4 = 2*1 + 32 + 4*16 = 98 g/mol. Mass = 3 moles x 98 g/mol = 294 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 (H) is approximately 1 g/mol, sulfur (S) is approximately 32 g/mol, and oxygen (O) is approximately 16 g/mol.
Step 4: Calculate the total mass: 2*1 (for H) + 32 (for S) + 4*16 (for O) = 2 + 32 + 64 = 98 g/mol.
Step 5: Now, to find the mass of 3 moles of H2SO4, multiply the number of moles (3) by the molar mass (98 g/mol).
Step 6: Perform the multiplication: 3 moles * 98 g/mol = 294 g.
Step 7: Therefore, the mass of 3 moles of sulfuric acid is 294 grams.
