Determine the density of cesium chloride which crystallises in bcc type structure with the edge length 412.1 pm.The atomic masses of Cs & Cl are 133 & 35.5 respectively. Solution) First calculate the molecular weight of CsCl ..then density = mass / volume. mass of unit cell = molecular mass/avogadro no.volume = (412.1)^3
NaOH + K2Cr2O7 ---> HCo + NaHCO3 ---> HCo + NaOH ---> CuSo4 + NaOH ---> CH3COOH + NaHCO3 ---> PbNO3 + KI --->
