roundup, an herbicide manufactured by monsanto, has the formula C3H8NO5P. How many moles of molecules are there in a 304.3 g sam
ple of Roundup?
1 answer:
First you find the molar mass of the formula.
3C: 36.03g + 8H:8.08g + N: 14.01g + 5O: 80g + P: 30.97g = 169.09g
Then do the mole ratio (304.3g)x(1mole/169.09g) = 1.800 moles

(g solute/g solution)*100 = % mass/mass
30 g / 400 * 100
0,075 * 100
= 7,5% w/w
hope this helps!
You basically just multiply those two and you get your answer that simple hope that helps
