Question

An alkaloid contains 17.28% of nitrogen and its molecular mass is 162 .The number of nitrogen atoms present in one molecule of the alkaloid is

Answer 1

There you go buddy:

Assume one molecule of alkaloid contains X number of nitrogen atoms

then percentage of nitrogen = 14X/162 X 100 = 2

so X  = 2

SO NUMBER OF NITROGEN ATOMS IN ONE MOLECULE OF ALKALOID IS 2

Molar mass of alkaloid 162 g Nitrogen 17.28% Mass of nitrogen (162×17.28)/100= 27.99 No.of nitrogen atom 27.99/14=2

In both the ways...the answer is 2.

Answer 2

Answer:

Assume one molecule of alkaloid contains X number of nitrogen atoms

then percentage of nitrogen = 14X/162 X 100 = 2

so X  = 2

SO NUMBER OF NITROGEN ATOMS IN ONE MOLECULE OF ALKALOID IS2

Molar mass of alkaloid 162 g Nitrogen 17.28% Mass of nitrogen (162×17.28)/100= 27.99 No.of nitrogen atom 27.99/14=2

In both the ways...the answer is 2.
