Asked by prachisharma772007 | 16 Jan, 2022, 11:12: AM
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 )
