The formula shows that there are three times as many atoms of hydrogen as of nitrogen in the compound. The gram atomic masses are 1.00794 for hydrogen and 14.0067 for nitrogen. Therefore, the percent by mass of hydrogen in the compound is 100{[3(1.00794)]/[3(1.00794) + 14.0067] or 17.7553 %, to the justified number of significant digits.

How many moles of hydrogen are needed to make 170000 g of ammonia?
170 kg = 170,000g NH3 = 170,000g / 17.0g/molNH3 = [10,000 molNH3] * 3moleH2 / 2moleNH3= 15,000 mole H2 needed to produce 170 kg NH3
How do you find molar mass of NH3?
To find the molar mass of NH3, you would add up the atomic masses of the atoms it contains. In this case, nitrogen (N) has a molar mass of around 14.01 g/mol and hydrogen (H) has a molar mass of around 1.01 g/mol. Therefore, the molar mass of NH3 would be approximately 14.01 + 3(1.01) = 17.03 g/mol.
What gas is made when hydrogen combines with nitrogen?
When hydrogen combines with nitrogen, it forms ammonia gas (NH3).
What is the formula mass of nitrogen hydride?

What is the mass percentage of hydrogen in ammonia?
The molar mass of ammonia (NH3) is 17.03 g/mol. Hydrogen's molar mass is 1.01 g/mol. The mass of hydrogen in ammonia is 3.03 g (3*1.01). To find the mass percentage of hydrogen in ammonia: (3.03 g / 17.03 g) * 100% ≈ 17.8%.
How many grams of hydrogen in are there in 150 g of ammonia?
In ammonia (NH3), there are three hydrogen atoms for every molecule. The molar mass of ammonia is 17 grams per mole. To find the mass of hydrogen in 150 grams of ammonia, you can calculate as follows: 150 g x (3 g H2 / 17 g NH3) = 26.47 g of hydrogen.
What are the compounds found in nh3?
NH3 is its own compound.The elements in NH3 are nitrogen and hydrogen.
What is the mass percentage of N in NH3?
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.
How do you calculate the percent by mass of NH3?
Grab yourself a periodic table and look up the atomic masses of nitrogen and hydrogen, which are the constituent elements of NH3 (which is ammonia.) Nitrogen is 14, and hydrogen is 1. Now look at the formula. It says you have 1 nitrogen and 3 hydrogens. Add it up: 14+1+1+1=17, for a total "molar mass" of 17 grams per mole. Now use the concept of percent (part divided by total) to get your percent composition by mass. 14/17=0.82, 82% nitrogen. 3/17=0.18, so 18% hydrogen. You can do that now for any compound!
How much does a mole of nh3 weigh?
nitrogen weighs 14, hydrogen weighs 1, so NH3 weighs 14+(3x1)=17grams
How do you find molar mass of NH3?
To find the molar mass of NH3, you would add up the atomic masses of the atoms it contains. In this case, nitrogen (N) has a molar mass of around 14.01 g/mol and hydrogen (H) has a molar mass of around 1.01 g/mol. Therefore, the molar mass of NH3 would be approximately 14.01 + 3(1.01) = 17.03 g/mol.
How many grams of hydrogen are there in 150 g of ammonia?
To determine the amount of hydrogen in 150 g of ammonia (NH3), we first need to calculate the molar mass of ammonia. The molar mass of NH3 is approximately 17 g/mol (1 nitrogen atom with a molar mass of 14 g/mol and 3 hydrogen atoms with a molar mass of 1 g/mol each). Next, we find the molar ratio of hydrogen to ammonia, which is 3:1. Therefore, in 150 g of ammonia, there are approximately 33.53 grams of hydrogen (150 g / 17 g/mol * 3 mol H2 / 1 mol NH3).
What is can the mass NH3 made if they give you the gram?
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.
How many moles are in 4.00g of NH3?
To find the number of moles in 4.00g of NH3, you first need to calculate the molar mass of NH3 (17.03 g/mol). Then, divide the given mass by the molar mass to get the number of moles. So, 4.00g / 17.03 g/mol = 0.235 moles of NH3.
