Question

Which of the following paris of gases contains the same number of molecules?
A. 16 g of `O_(2)` and 14 g of `N_(2)`
B. 8 g of `O_(2)` and 22g of `CO_(2)`
C. 32 g of `O_(2)` and 32 g of `N_(2)`
D.

Answer 1

a) 16 g of `O_(2)` = 0.5 mol = `(N_(A))/2` molecules
14 g of `N_(2)` = 0.5 mol = (N_(A))/2 molecules
