Look on a Periodic Table. If you have different isotopes then you need to multiply the mass number and atomic number and then find the average of them and you'll have the average Atomic Mass which is the same as on the periodic table. The location of the mass number on a periodic table depends but it's normally the one with a decimal.

How do you find moles of hydrogen?
To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).
What is the mass percent of hydrogen in ammonium phosphate NH4 3PO4?
To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.
How many moles are in 12G hydrogen?
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
How the atomic mass of hydrogen can be find out?
Look in a periodic table.
What is the percent composition of hydrogen in NH4HCO3?
To find the percent composition of hydrogen in NH4HCO3, we first calculate the molar mass of the compound. NH4HCO3 has a molar mass of 79.06 g/mol. The molar mass contribution of hydrogen is 1.01 g/mol. To find the percent composition of hydrogen, we divide the molar mass contribution of hydrogen by the molar mass of NH4HCO3 and multiply by 100: (1.01 g/mol / 79.06 g/mol) x 100 ≈ 1.28%.
What is the percentage by mass of hydrogen in ammonia?
Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%
What is percent of hydrogen in sulfuric acid?
Sulfuric acid (H₂SO₄) contains two hydrogen atoms in the molecule. To find the percentage of hydrogen in sulfuric acid, divide the atomic mass of hydrogen by the molar mass of sulfuric acid and multiply by 100. This calculation gives approximately 2.03% hydrogen in sulfuric acid by mass.
If 9.0g of water contain 1.0g of hydrogen what mass of oxygen is contained in 36g of water?
What an odd question. Well, whatever. The question shows that 1/9 of the solution is hydrogen. So it must be said that 8/9 is water (assuming the sample comprises solely of hydrogen and water)36/9 = 44 x 8 = 32So 32g of it is oxygen.
What is the mass number for hydrogen?
the relative atomic mass for hydrogen is 1.0079 amu.
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%.
Which element has the lowest mass on the periodic table?
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
An atomic mass for hydrogen?
atomic mass for hydrogen is 1.00794.
