Sure! Here are the step by step solutions for finding the root-mean-square velocity of and gases at a given temperature:
For :
1. Use the formula for root-mean-square velocity: , where is the gas constant, is the temperature in Kelvin, and is the molar mass of the gas.
2. Substitute the values given: , , and (the molar mass of ).
3. Convert the molar mass to kilograms per mole: .
4. Plug in the values and solve for :
Therefore, the root-mean-square velocity of at is approximately .
For :
1. Use the same formula for root-mean-square velocity: , but with the molar mass of , which is .
2. Substitute the values given: , and .
3. Solve for by setting the two expressions for equal to each other:
where is the temperature at which the root-mean-square velocity of was calculated (in this case, ).
4. Substitute the value of back into the formula for and solve:
Therefore, the root-mean-square velocity of at
