Question

117. When 0.44 g of a colourless oxide of nitrogen
occupies 224 mL at 1520 mm Hg and 273°C,
then the oxide is​

Answer 1

Answer:

Explanation:

=> It is given here,

=> Mol weight of  colourless oxide of nitrogen = 0.44 g

=> It occupies 224 mL at 1520 mm Hg and 273°C,

=> the oxide = ?​

=> 22400 ml contains 1 mol then 224 ml contains :

= 224 * 1 / 22400

= 0.01 mol

=> 0.01 mol weights 0.44 g then weights of 1 mol :

= 1 * 0.44 / 0.01 = 44 g  

Thus, the oxide is 44 g.
