What is the average velocity of atoms in 1.50 mol of neon (a monatomic gas) at 278 k? for m, use 0.01500 kg. remember that r = 8.31 j/(molk).

a. 9610 m/s
b. 832 m/s
c. 6.93 m/s
d. 693,000 m/s

B. 832 m/s

Explanation:

(1/2) (0.015) v^2 = (3/2) (1.5) (8.31) (278)

0.0075 v^2 = 5197.905

v^2 = 693054

v = 832.49
