What is KNO3 used for in horticulture? How do i work out how many moles a chemical is?

to determine moles of a chemical, u must know the mass in terms of grams. then multiply this number by 1/molecular weight

or simply divide it by molecular weight.

Well take OH- . i cant remember the atomic mass of O so im gonna round, i think its 16. H is 1.007.

H= 1.007

O= 16

17.007(g)

 

if u have 10 grams of the compound, either multiply

 

10.000g x 1/17.007

 

OR

 

divide

 

10.000g/17.007

 

the answer is .588 mol

 

or if u have molarity and volume, u can determine mol this way as well. Take M(molarity) and multiply by L(liters)

 

MV= moles
