Which of the following is not correct regarding 14 g gram of carbon nonoxide?A. It corresponds to `0*5` mole of COB. It occupies `2*24` litres at S.T.P.C. It corresponds to `3*01xx10^(23)` molecules of COD. It corresponds to same number of moles of `CO_(2)` and nitrogen (I) oxide gases |

Answer» Correct Answer - B (A) Mol mass of CO = 28 `:.` 14 g CO = 1/2 mol of CO (B) 28 g of CO at S.T.P. `= 22*4 L` 14 g of CO at S.T.P. `=11*2 L` (C) 14 g of CO `= (14)/(28) = 0*5` mol `= 11*2L` at S.T.P. `=3*01xx10^(23)` molecules. (D) Mol. mass of `CO_(2)` = Mol mass of `N_(2)O = 44` |
