Well let's see:
H = 1g
O = 16g
N = 14g
H2O = 18g per mole (1 + 1 + 16)
NH3 = 17g per mole (14 + 1 + 1)
18 x 5 = 90
17 x 3.5 = 59.5
90>59.5
.: 5.0 mol H2O has a greater mass than 3.5 mol of NH3
H20 is water.HF is hydrogen fluoride.NH3 is ammonia.
To find the mass of NH3 produced, first calculate the number of moles of NH3 using the given mass and the molar mass of NH3. Then, use the relationship between moles and mass (mass = moles x molar mass) to find the mass of NH3.
17 g/mol is the molecular mass of ammonia NH3.
gas: NH3water solution: NH3 + H20 NH4OH
Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table.
H20 ice and, its liquids H20/NH3.
H20 is water.HF is hydrogen fluoride.NH3 is ammonia.
Nh3 + h20 <-> nh4+ + oh-
The percent by mass of hydrogen in NH3 is 17.65%. This can be calculated by dividing the mass of hydrogen in NH3 by the total mass of NH3 and then multiplying by 100.
To find the mass of NH3 produced, first calculate the number of moles of NH3 using the given mass and the molar mass of NH3. Then, use the relationship between moles and mass (mass = moles x molar mass) to find the mass of NH3.
17 g/mol is the molecular mass of ammonia NH3.
Atomic mass of NH3 is 17.So there are 1.353mol.
gas: NH3water solution: NH3 + H20 NH4OH
Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table.
The molecular mass of ammonia (NH3) is 18.03 grams/mole
The molar mass of ammonia gas (NH3) is approximately 17.03 g/mol.
To find the number of moles of NH3 in 107.1g, divide the given mass by the molar mass of NH3. The molar mass of NH3 is 17.03 g/mol. ( \frac{107.1 , \text{g}}{17.03 , \text{g/mol}} ≈ 6.29 , \text{mol} ) of NH3 are present.
