Answer to Question #140163 in General Chemistry for Dylan

Question

A sample of gas was found to occupy 37.82 L under conditions of 432 kPa and 453 K.  What is the identity of this diatomic gas? The mass of the gas was found to be 139 grams.

Answer 1

sample of gas was found to occupy 37.82 L

under conditions of 432 kPa and 453 K. 

The mass of the gas was found to be 139 grams.

Therefore:

((37.82)(432))/ 453 = 139

16338.24 b /453 = 139

36.07b = 139

b = 139/36.07

b = 3.85g

M_Co2 = 3.85g
