How many atoms are in 1 amu and 1 g of hydrogen?
1 g hydrogen (H) has 6,022 140 857.10e23 atoms.
How many number of neon atom in 300 amu of neon?
Devide mass by atomic mass to get 15 atoms Ne 300 (amu) / 20.2 (amu/atom Ne) = (14.9 atoms) = 15 atoms (= 303 amu)
What is the mass number for hydrogen?
the relative atomic mass for hydrogen is 1.0079 amu.
What is the number of sulfur atoms that equal a mass of 32.07 amu?

How many oxygen atoms are present in 96 amu ozone?
96(amu) / 16.0(amu / atom O) = 6 atoms O
How many atoms are in 1 amu and 1 g of hydrogen?
1 g hydrogen (H) has 6,022 140 857.10e23 atoms.
How many atoms are in 1 amu and 1 g of hydrogen (h)?
1 g hydrogen (H) has 6,022 140 857.10e23 atoms.
How many number of neon atom in 300 amu of neon?
Devide mass by atomic mass to get 15 atoms Ne 300 (amu) / 20.2 (amu/atom Ne) = (14.9 atoms) = 15 atoms (= 303 amu)
What is the mass number for hydrogen?
the relative atomic mass for hydrogen is 1.0079 amu.
What is the empirical formula weight of HO?
The Empirical formula simply means that it is the lowest ratio of atoms, not the number of atoms. Therefore, because the ratio of Hydrogen atoms to Oxygen atoms is 1:1, the weight of this is the same as normal:1.008 + 16 = 17.008 amu
In the compound Cu2OH2CO3 which element is present with the largest percent by mass?
From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
What is the number of sulfur atoms that equal a mass of 32.07 amu?

How you calculate atomic mass unit?
Step 1: Write out the chemical formula of the compound whose atomic mass you want to calculate. The chemical formula provides the number of atoms in one molecule of a compound (i.e. the chemical formula for water is H2O). For example, the chemical formula of phosphate is H3O4P.Step 2: Look up the atomic mass for each individual element in the given compound on the periodic table. This number is commonly found just below the letter symbol for the element. For our example, the atomic mass of hydrogen (H) is 1.008 amu per atom, oxygen (O) is 16.00 amu per atom and phosphorous (P) is 30.97 amu per atom.Step 3: Multiply the result for every atom in Step 2 by the number of atoms in one molecule of the compound. Phosphate contains three atoms of hydrogen, four atoms of oxygen and one atom of phosphorous in one molecule. So for phosphate the calculations would be as follows; 1.008 amu/atom x 3 hydrogen atoms per molecule = 3.024 amu of hydrogen per molecule, 16.00 amu/atom x 4 oxygen atoms per molecule = 64.00 amu of oxygen per molecule and 30.97 amu/atom x 1 phosphorous atom per molecule = 30.97 amu of phosphorous per molecule.Step 4: Add the numbers calculated for each atom in Step 3 together to determine the total amu for one molecule of the compound. So for phosphate the atomic mass is 3.024 + 64.00 + 30.97 = 97.99 amu in one molecule of phosphate.
How many energy give 1 hydrogen atom when it fused?
If it is being fused it must be fused with something. If 2 atoms of hydrogen (deuterium) fuse to form one atom of helium then there is a difference of mass of (2.0141 x 2) amu - 4.002602 amu = 0.025598 amu 0.025598 amu x ( 931 Mev / amu) = 23.831738 Mev So if you want an amount per atom of hydrogen, divide by 2. 11.92 Mev per deuterium atom
How many oxygen atoms are present in 96 amu ozone?
96(amu) / 16.0(amu / atom O) = 6 atoms O
How many grams of nitrogen are there in NH4NO3?
Firstly, find the percent composition of hydrogen in the compound (ammonium nitrate). So we have: 2 x Nitrogen atom = 28.02 amu 4 x Hydrogen atoms = 4.04 amu 3 x Oxygen atoms = 48.00 amu Total of: 80.06 amu or g/mol % H = 4.04 g/mol ÷ 80.06 g/mol = 0.050462153385 = 5.05 % (sig. figs.) Then, we take the percentage of hydrogen and multiply it by the mass of the substance. 50.00 g NH4NO3 x 0.050462153385 = 2.52310766925 = 2.52 g H So, there is 2.52 g of hydrogen in 50.00 g of NH4NO3
How much does one water molecule weight?
The mass of any molecule is equal to the sum of the Atomic Mass Units of all of its constituent atoms. Atomic Mass Unit values may be found on any Periodic Table. In this case, a water molecule consists of two Hydrogen atoms and one Oxygen atom. Hydrogen has a mass of approximately 1 AMU. Oxygen has a mass of approximately 16 AMU. Therefore, the mass of one molecule of water is approximately 18 AMU (or 18.01528 AMU exactly). What does this number mean? If you had exactly 6.022 x 10^23 molecules of water, it would weigh 18 grams.
