how many times as large is the approximite radius of a mercury atom, 1.50*10^-10 meter, as the approximite radius of a hydrogen atom, 2.5*10

Actually these are representative of the approximate radii of the atoms.

 See https://www.webelements.com/hydrogen/atom_sizes.html and https://www.webelements.com/mercury/atom_sizes.html for example.

OMG PLEASE HELP ME I DONT GET IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is a very simple division problem. Simply divide 1.5x10^-10 by 2.5x10^-11 which is 6 meaning the Mercury atom is 6 times larger than a hydrogen atom. 

Thanks, radio.......

Radio, you really should tune your dial to a different station and move your antenna for good measure, else you’ll keep tuning into the same troll.

This question is BS, like the last one, only with different numbers. None of the values are close to the radii of any atom.

OMG!! Why don't you believe me I don't know how else to do it pretty please with googly eyes on top.

Your time is yours to waste :/

Who are we going to believe.  Alan or our friendly neighbourhood troll ?     

Alan has back up evidence... The troll has googly eyes....  Mmm it IS a tough one!!

Anyway I think i will give you thumbs up anyway Mr Troll.  You are entertaining.  :))
