A SAMPLE CONTAINS 200 ATOMS OF HYDROGEN, O.O5 GRAM ATOM OF NITROGEN ,10 TO THE POWER -20 GRAM OF OXYGEN.WHAT IS THE APPROXIMATE NO.OF TOTAL ATOMS ?
Number of hydrogen atoms = 200
Gram atom of nitrogen = 0.05g
14 grams atom of nitrogen = 6.0221023 atoms of nitrogen
Now 0.05 grams atom of nitrogen will have =
Oxygen = 10-20 g
16 grams of oxygen = 6.0221023 atoms of oxygen
10-20 grams of oxygen will have =
Total number of atoms = 200 + (0.02151023) + 376.38 = 2.151021 atoms
Gram atom of nitrogen = 0.05g
14 grams atom of nitrogen = 6.0221023 atoms of nitrogen
Now 0.05 grams atom of nitrogen will have =
Oxygen = 10-20 g
16 grams of oxygen = 6.0221023 atoms of oxygen
10-20 grams of oxygen will have =
Total number of atoms = 200 + (0.02151023) + 376.38 = 2.151021 atoms
