Molar and molecular weight of CH3HgCl

• Molecular formula: CH3HgCl or CH3ClHg
• Relative molecular weight of CH3HgCl: 251.07752
• Molar mass of CH3HgCl: 251.07752 g/mol (0.25108 kg/mol)

Calculation of the relative molecular and molar mass of CH3HgCl

• Mr[CH3HgCl] = Ar[C] + Ar[H] * 3 + Ar[Cl] + Ar[Hg] = 12.0107 + 1.00794 * 3 + 35.453 + 200.59 = 251.07752
• Molar mass (kg/mol) = Mr[CH3HgCl] : 1000 = 251.07752 : 1000 = 0.25108 kg/mol
