HELP! PLZ

2H2(g) + S2(g) ¡ê 2H2S(g) Analysis of the contents of a 15.0L flask reveals that there are 4.4 moles of hydrogen gas, 2.0 moles of sulfur gas, and 3.7 moles of hydrogen sulfide gas in the flask at equilibrium. Calculate the equilibrium constant K

i got an answer of 39.776 because i did [mol/L H2S]^2/ [mol/L H2]^2[mol/L S2]^2 so im not sure what went wrong

i used those exact numbers

after squaring i ended up with 0.060844444/ (1.529679004 *10^(-3)) = 39.7759555

4.4/15= 0.293333333 2/15= 0.133333333 3.7/15= 0.246666666

why don't we square the bottom numbers to?

also I got 1.556 but LON CAPA is telling me that is incorrect

okay with the squared H2 it is 11.67414 but again LON CAPA is saying it is incorrect

Doing that i get answer to be 1.56 but again it says incorrect

nevermind answer is 5.3 i had to square H2 which was (0.2933) and then multiply. Thank for everything Dr.Bob :)
