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?

Respuesta :

Answer:

3.830177515 moles

Explanation:

You have :

  • 647.3 g of Roundup
  • Molar mass of Round up which is equal to 169 g.mol
  • and the formula: n=m/M

Therefore: n=647.3/169

=3.830177515 moles
