thE INCREASING ORDER OF MASS AMONG THE FOLLOWINHG IS 1.1000u OF CO2 2.1 MOLE OF SILVER 3.2g atom of magnesium 4,4.48dm^3 of nitrogen gas |
| 1000 u of CO2 = 1.66 X 10-21g 1 mol of silver = 108 g 1 g atom of magnesium = 24 g So, 2 g atom of magnesium = 48 g 4.48dm3 nitrogen=4048 l nitrogen 22.4 l nitrogen at S.T.T = 1 mol Hence 1 l nitrogen at S.T.T = 1/22.4 mol So, 4.48 l nitrogen at S.T.T = 1/22.4 × 4.48mol = 0.2 mol 1 mol of nitrogen = 28 g 0.2 mol mol of nitrogen = 28 x 0.2 = 5.6 g Hence the order is 1 mol of silver > 2 g atom of magnesium > 4.48 dm3 of nitrogen > 1000u of CO2 |
