Question

AN ORGANIC COMPOUND ON ANALYSIS WAS FOUND TO CONTAIN 0 014%OF
NITROGEN IF IT'S MOLECULE CONTAINS 2 NITROGEN ATOMS ,THEN THE
MOLECULAR MASS OF THE COMPOUND

veena Vasandani · Accepted Answer

Assume that the molecular mass of the compound is
x
0 014% of x is the mass of 2 nitrogen
atoms

Mass of 2 N atoms = 2 × 14= 28u or
28g
Therefore, 0 014 ×
x × 100 = 28
x =28 × 1000
014
0 014x = 2800
x = 200000g
