Question

rms speed of hydrogen molecule at 27°C:
(a)
193 kms -1
(b)
1.93 kms -1
(c)
19.3 kms - 1
(d) 0.193 kms -1​

Answer 1

Answer:

are you 11th.?

Explanation:

Answer 2

THE RMS SPEED OF HYDROGEN AT 25°C IS 1.93KM/S

The RMS speed which is the root mean square speed of nay gaseous molecule is given by:-

                                     V=$\sqrt{\frac{3RT}{M} }$

• WHERE R= universal gas constant=

• T = Temperature

• M= Molecular weight of gaseous molecule

• In this question we have to calculate this speed for hydrogen molecule

• M = 0.002 kg/mol

• T = 273+27= 300 K

• Putting above in formula  we get  V= 1.93 km/s
