[ 11:53:01 PM ] Guest : A certain nonmetal reacts with hydrogen at 440 ∘C to form a poisonous, foul-smelling gas. The density of the gas at 25 ∘C and 1.00 atm is 3.309 g/L. What is the formula of the gas? [ 11:53:40 PM ] Tutor : Hi this is Helen chemistry tutor [ 11:53:47 PM ] Guest : Hey Helen, how are you? [ 11:53:49 PM ] Tutor : I can see your question [ 11:53:56 PM ] : please wait let me look at it [ 11:53:58 PM ] Guest : Sure [ 11:55:01 PM ] Tutor : so we can use density ,temperature and pressure to find the molar mass of the gsas [ 11:55:03 PM ] : gas [ 11:55:09 PM ] Guest : Ok [ 11:55:09 PM ] Tutor : ideal gas law is used [ 11:55:21 PM ] : Pv=nRT [ 11:55:26 PM ] : n =mass /molar mass [ 11:55:29 PM ] Guest : Ok [ 11:56:08 PM ] Tutor : look at he boar [ 11:56:10 PM ] : board [ 11:56:25 PM ] Guest : watching [ 11:58:04 PM ] : Still watching [ 11:58:18 PM ] : If you are busy, you can just give the final answer and I can do the work [ 11:58:45 PM ] Tutor : ok [ 11:59:39 PM ] Guest : So final is?

[ 12:07:44 AM ] Tutor : hi molar mass is 81 [ 12:07:53 AM ] : if the mass of Br is 79g [ 12:07:58 AM ] : mass of H will be 1g [ 12:08:02 AM ] : so it has to be HBr [ 12:08:59 AM ] Guest : It's not HBr [
