hey friend
molar mass KNO3 = 101 g/mol
1kg = 1000 g
1000 g x 1 mol/101 g = 9.9 moles KNO3
Each moles KNO3 contains 1 moles N
9.9 moles KNO3 x 1 mol N/mole KNO3 = 9.9 moles N
mass N = 9.9 moles x 14 g/mole = 138.6 grams N
molar mass KNO3 = 101 g/mol
1kg = 1000 g
1000 g x 1 mol/101 g = 9.9 moles KNO3
Each moles KNO3 contains 1 moles N
9.9 moles KNO3 x 1 mol N/mole KNO3 = 9.9 moles N
mass N = 9.9 moles x 14 g/mole = 138.6 grams N
