प्रश्न
Calculate the relative molecular masses of the following
CHCI3
[At mass : C = 12, H = 1, O = 16, Ci = 35.5, N = 14, Cu = 63.5, S = 32, K = 39, Pt = 195, Ca = 40, P = 31, Mg = 24]
उत्तर
molecular mass of chloroform (CHCl3)
= mass of carbon + mass of hydrogen + 3 x mass of chlorine
= 12 + 1 + 3 x 35.5
= 119.5g
