What is the mass percentage of ammonium hydrogen phosphate?
The chemical formula is (NH4)HPO4 (if you think to this phosphate). The molar mass is 132,07. The percentages of the elements are: - hydrogen: 6,86997 % - nitrogen: 21,21196 % - oxygen: 48,45843 % - phosphorous: 23,45964 %
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
What is the formula mass for a compound with a molecular formula of C6H14?
The formula mass for a compound is calculated by adding up the atomic masses of all the atoms in the formula. For C6H14, the atomic mass of carbon (C) is 12.01 g/mol and the atomic mass of hydrogen (H) is 1.008 g/mol. Therefore, the formula mass would be 6(12.01) + 14(1.008) = 86.18 g/mol.
Percent of hydrogen in methane?
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25
What is the formula mass and chemical formula for ammonium nitrate?
The chemical formula of ammonium nitrate is NH4NO3.The molecular mass is 80,052 g.
What is the formula mass and chemical formula for sodium hydrogen carbonate?
The chemical formula of sodium hydrogen carbonate is NH4HCO3.The molecular mass is 84,0066 g.
What are the relative formula masses of hydrogen molecules?
The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.
What is the percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate NaHCO3?
The percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate (NaHCO3) is 27,38 %.

What is the mass percent of H in ammonium bicarbonate?
The molecular formula of ammonium bicarbonate is NH4HCO3. To find the mass percent of hydrogen (H) in it, we calculate the molar mass of hydrogen in the formula and divide it by the molar mass of the whole compound NH4HCO3, then multiply by 100. The mass percent of hydrogen in ammonium bicarbonate is approximately 5.9%.
What is the formula mass of nitrogen hydride?
Nitrogen hydride has the chemical formula of NH3 The gram formula mass of nitrogen is approximately 14.0 g/mole & the gram formula mass of hydrogen is approximately 1.0 g/mole In the chemical formula, you have 1 nitrogen atom and 3 hydrogen atoms 14.0 + 1.0 + 1.0 + 1.0 = 17.0 g/mole
What percentage by mass of table sugar is hydrogen?
Table sugar (sucrose) has a molecular formula of C12H22O11, which means it is composed of carbon, hydrogen, and oxygen. To calculate the percentage by mass of hydrogen in table sugar, divide the mass of hydrogen by the total mass of the compound and then multiply by 100. In this case, hydrogen has a total mass of 22 g/mol out of a total molecular mass of 342 g/mol, which gives a percentage of approximately 6.4% hydrogen by mass in table sugar.
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 2:1. To find the empirical formula, divide the moles of each element by the smallest number of moles, which is 0.059 mol for hydrogen. This gives a ratio of 1:0.5 for hydrogen and oxygen, which simplifies to the empirical formula H2O. To find the molecular formula, calculate the molecular mass of H2O (18 g/mol) and divide the given molecular mass (34 g/mol) by the empirical formula mass to get the multiplier of 2. So, the molecular formula of the compound is H2O2.
What is the formula mass for the ammonium ion?
The formula mass of the ammonium ion, NH4+, is calculated by adding the atomic masses of the elements in the formula. For NH4+, the atomic mass of nitrogen (N) is 14.01 and the atomic mass of hydrogen (H) is 1.01. Therefore, the formula mass is 14.01 + (4 x 1.01) = 18.05 g/mol.
Is hydrogen lighter than aspirin?
Yes, definitely. The formula for aspirin, or acetylsalicyclic acid, is C9H8O4, having a molecular mass of 180.157 g/mole. Hydrogen's formula is H2, having a molecular mass of 2.02 g/mole. So if you had a liter of hydrogen and an equal amount of molecules of aspirin, the hydrogen would be about 1/5 of a kilogram lighter.
