Roundup, a herbicide manufactured by Monsanto, has the formula C3H8NO5P. How many moles of molecules are there in a 647.3-g sample of Roundup? I got the answer 2.305 x 10^24 but for some reason it’s not working. Is it the wrong one?

3.830177515 moles

Explanation:

You have :

Therefore: n=647.3/169

=3.830177515 moles

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
