(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the speed of sound waves in hydrogen gas (M = 2.00 g/mol and γ = 1.40) at T = 300 K.

2. Relevant equations

v = root (γRT/M)

3. The attempt at a solution

I keep getting 1321.4km/s but its not being acccepted (automated homework) so Im pretty sure this is a sig fig error.

I converted M into kg/mo (2/1000) = .002kg/mol

and my answer seems reasonable also.

the least amount of sig figs is M, which is 3

so my answer should also be 3 digits right? so 1.32e3 .. please help. thanks
