## Homework Statement

Compute the rms speed of a nitrogen molecule of 35.0 celcius.

## Homework Equations

V(rms) = sqrt((3RT)/M)

## The Attempt at a Solution

I plugged in 8.31 for R and 308 K for T and 14.0 g/mol for M. I arrived at a solution of 23.4 m/s but this answer came back as incorrect in online homework. However, I used this value to complete parts b and c to this question and correctly completed them. What gives?
