How do you find the molar mass of cacl2?
Expert Answer:
- CaCl2 molecule has one Calcium ( Ca ) atom and two chlorine ( Cl ) atoms.
- Relative atomic mass of Ca = 40.08.
- Relative atomic mass of Cl = 35.45.
- Hence , Moleculer mass of CaCl2 = 40.08 + ( 2 × 35.45 ) = 110.98 amu ≈ 111 amu.
- ( 1 amu = 1.660 × 10-27 kg )
