I can not figure out how many mols are in 102grams of NH3?
mols = grams/molar mass.
mols NH3 = 102/17 = ??
To find the number of moles in 102 grams of NH3, you need to use the formula mols = grams/molar mass.
First, you need to determine the molar mass of NH3 (ammonia). NH3 is composed of one nitrogen atom (N) with an atomic mass of approximately 14 grams per mole (g/mol) and three hydrogen atoms (H) with an atomic mass of approximately 1 g/mol each.
The molar mass of NH3 can be calculated as follows:
(1 x Nitrogen atomic mass) + (3 x Hydrogen atomic mass) = (1 x 14 g/mol) + (3 x 1 g/mol) = 14 g/mol + 3 g/mol = 17 g/mol.
Now you can use the formula:
mols NH3 = grams/molar mass
mols NH3 = 102 grams / 17 g/mol
Divide 102 by 17 to find the number of moles:
mols NH3 = 6 moles.
Therefore, there are 6 moles of NH3 in 102 grams of NH3.
