Formula Used
Molar mass equals each atomic mass times its atom count.
M(CCl4) = M(C) + 4 × M(Cl)
Mass equals moles multiplied by the calculated molar mass.
mass = moles × molar mass
Moles equal sample grams divided by calculated molar mass.
moles = mass ÷ molar mass
Step-by-Step Calculation
- Carbon contributes 1 × 12.011 = 12.011 g/mol.
- Chlorine contributes 4 × 35.45 = 141.800 g/mol.
- Total molar mass equals 153.811 g/mol.
- One mole contains 6.02214076 × 10²³ molecules.

About the CCl4 Molar Mass Calculator
Carbon tetrachloride has one carbon atom and four chlorine atoms. Its chemical formula is written as CCl4. Molar mass describes one mole of a substance. The value uses atomic masses from the periodic table. This calculator multiplies each atomic mass by its atom count. Carbon contributes one atomic mass to the total. Chlorine contributes four times its listed atomic mass. The standard rounded result is about 153.811 grams per mole. Different reference datasets can produce slightly different final values. Those differences usually come from atomic weight rounding. The calculator also shows each element's percentage contribution. Carbon supplies a small fraction of the total mass. Chlorine supplies most of the compound's molar mass. These percentages help with composition and stoichiometry exercises.

Understanding the CCl4 Calculation
The formula contains one carbon and four chlorine atoms. Start with carbon's atomic mass of 12.011. Then multiply chlorine's 35.45 value by four. That chlorine contribution equals 141.800 grams per mole. Add both contributions to get 153.811 grams per mole. Mass conversions then use this calculated molar mass. One mole therefore has about 153.811 grams of CCl4. Two moles have about twice that sample mass. Half a mole has about half that mass. Particle calculations use Avogadro's constant for molecule counts. Each CCl4 molecule contains exactly one carbon atom. Each molecule also contains exactly four chlorine atoms. Therefore chlorine atom counts are four times molecule counts.
Why Molar Mass Matters
Molar mass connects measurable laboratory mass with particle quantities. It supports reaction calculations, composition work, and solution preparation. Students often use it before solving stoichiometry problems. Teachers use it to demonstrate formula interpretation and atomic contributions. Reliable atomic values improve consistency across repeated calculations. Carbon tetrachloride also requires careful chemical handling. It is toxic and presents serious exposure risks. Calculator results should support learning, not unsafe chemical use. Follow laboratory guidance and current safety documentation for real handling. Use reliable atomic weights for consistent chemistry calculations today.
