Chemical Formula

Enter a chemical formula to calculate its molar mass

Molar Mass Calculation:

H₂SO₄ = (2 × 1.008) + (32.06) + (4 × 15.999)

= 2.016 + 32.06 + 63.996

= 98.072 g/mol

Total Molar Mass:

98.072 g/mol

Limiting Reagent Analysis:

For reaction: 2H₂ + O₂ → 2H₂O

Moles of H₂: 10 g / 2.016 g/mol = 4.96 mol

Moles of O₂: 50 g / 32.00 g/mol = 1.56 mol

H₂ requires O₂: 4.96 mol H₂ × (1 mol O₂/2 mol H₂) = 2.48 mol O₂

O₂ available (1.56 mol) < O₂ required (2.48 mol)

Limiting reagent: O₂

Theoretical Yield:

56.2 g of H₂O
