Expert Solution

Step 1 To Calculate

$G i v e n, t e m p e r a t u r e = 25 ° C = (25 + 273.15) K = 298.15 K M o l a r m a s s o f n i t r i c o x i d e = 30.01 g / m o l = 0.03001 k g / m o l g a s c o n s \tan t = 8.314 \frac{J}{m o l . K} w e a r e a s k e d t o c a l c u l a t e t h e V_{r m s} f o r n i t r i c o x i d e a t 25 ° C$

Step 2 Formula used and Calculations

$T h e V_{r m s} o f n i t r i c o x i d e g a s i s g i v e n b y, V_{r m s} = \sqrt{\frac{3 R T}{M}}; w h e r e, R i s g a s c o n s \tan t, T i s t e m p e r a t u r e a n d M i s m o l a r m a s s o f g a s . N o w, V_{r m s} = \sqrt{\frac{3 R T}{M}} V_{r m s} = \sqrt{\frac{3 \times 8.314 \frac{J}{m o l . K} \times 298.15 K}{0.03001 \frac{k g}{m o l}}} V_{r m s} = \sqrt{\frac{7436.4573 \frac{k g . m^{2}}{s e c^{2}}}{0.03001 k g}} (1 J = 1 \frac{k g . m^{2}}{s e c^{2}}) V_{r m s} = \sqrt{247799.3102 \frac{m^{2}}{s e c^{2}}} V_{r m s} = 497.794 \frac{m}{s e c} V_{r m s} = 497.8 \frac{m}{s e c} T h u s, t h e V_{r m s} f o r n i t r i c o x i d e a t 25 ° C w o u l d b e, 497.8 \frac{m}{s e c}$
