Calculate the number of molecules in 1 kg of Calcium Chloride.
Asked by aashimegh | 28th Aug, 2019, 05:25: PM
Mass of calcium chloride = 1 kg
= 1000 gm
Molar mass of calcium chloride = 110.98 gm/mol
No. of moles of calcium chloride
No. of molecules of CaCl2 = No. of moles of CaCl2 × Avogadro's number
= 9.01 × 6.022 × 1023
=5.42 × 1024 molecules of CaCl2
