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 mass percentage of hydrogen in ammonia?
The formula for ammonia is NH3, and to a reasonable approximation, the atomic weight of hydrogen is 1 and that of nitrogen is 14. Therefore, the % hydrogen = 100(3/17) = 18 %.
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 %
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
What is the name of the covalent compound BH3?
Mass?Here it is with an example.. a compound of 78.14% Boron and 21.86% hydrogen with an experimental mass of 27 to 28 g. The empirical formula is as above BH3and Molecular formula is B2H6Molar mass / by empirical formula mass should give you an integer to multiply the empirical formula (BH3) with. This time it was 2 (rounded).
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 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 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.
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
Why are low- formula-mass alcohols soluble in water?
because of the polarity of the oxygen-hydrogen bond
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.
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
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
The empirical formula for cumene a compound containing only carbon and hydrogen is C3H4. Its Molecular mass is 120 g. What is the molecular formula for cumene?
This molecular formula is C9H12.
Empirical formula of CuO using hydrogen gas?
It depends upon the mass of both your copper and oxygen.
What is the formula of H2?
H2S is the formula of Hydrogen sulfide.
What is the mass percentage of hydrogen in ammonia?
The formula for ammonia is NH3, and to a reasonable approximation, the atomic weight of hydrogen is 1 and that of nitrogen is 14. Therefore, the % hydrogen = 100(3/17) = 18 %.
