What is the molecular formula of a compound with the empirical formula C2H3N if its molar mass is about 123.15 g/mole? For your answer simply put subscripts directly after the element's symbol. You do not need to put anything for a subscript of '1'. For example, if your answer is supposed to be 'C2H2N2' then you would input 'C2H2N2'. Your answer should be written Carbon first, Hydrogen second, and Nitrogen third.

i have no clue hope you find the answer

2b2t

explanation:

2b2t

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
