Question

The root mean square of a certain sample of carbon dioxide molecules with a molecular mass of 44g/mole is 396m/s.What is the root maen square of water vapour molecules with a molecular weight of 18g/mole at the same temperature

Answer 1

Answer:

607.2 m/s

Explanation:

We know that the RMS Velocity is Root (3RT/M)

So for first case, use this formula to get value of root(3rt) and substitute in the second one to get the answer.

M will b molecular mass.
