A gaseous mixture contains \( \mathrm{CO}_{2}(\mathrm{~g}) \) and \( \mathrm{N}_{2} \mathrm{O}(\mathrm{g}) \) in a \( 2: 5 \) ratio by mass. The ratio of the number of molecules of \( \mathrm{CO}_{2}(\mathrm{~g}) \) and \( \mathrm{N}_{2} \mathrm{O}(\mathrm{g}) \) is
(A) \( 5: 2 \)
(B) \( 2: 5 \)
(C) \( 1: 2 \)
(D) \( 5: 4 \)
