I apologize if this seems much too "freshman", and may come across as annoyingly simple to some more trained or educated on this board. However I will ask the question anyways as I have failed to find an answer elsewhere.
Under Newton's Second Law of Motion, f=ma.
thus F = kg (m/s^2)...
I used the "1.94 times" information given from the problem to find the molecular mass of the compound after finding the vapor density formula on wikipedia.
(32g/mol O2/2.016g/mol H2) = 15.873
15.873*1.94 = 30.8 .
30.8 *2.016 = 62.1 g/mol (molar mass of the gaseous binary compound)
So I have...
Homework Statement
"A gaseous binary compound has a vapor density that is 1.94 times that of oxygen at the same temperature and pressure. When 1.39g of the gas is burned in an excess of oxygen, 1.21 g water is formed, removing all the hydrogen originally present.
(a) Estimate the molecular...
