the root mean square speed of a certain gaseous oxide is 493 m/s at 20 C. what is the molecular formula of the compound.
how is the answer NO???
Did you get 0.030? I suspect you did. The answer is in kg/mol which means 30 g/mol. Then 30-16 means 14 for the other element and that's N. (Note the problem tells us its is an oxide.)
how come it cant be COH2...it has a mm of 30 also right??
it cannot be COH2 because it's an oxide NOT a hyrdoxide. note the difference between the two.
