What is the molar mass of nicotine C10H14N2?
The molar mass of nicotine is 162.23 grams per mole. Its chemical formula is C10H14N2. Nicotine is a alkaloid found in the leaves of certain plants like the tobacco plant that has the scientific name Nicotinia tabaum.
What is the percentage by the mass of hydrogen in (NH4)2SO4?
The molar mass of (NH4)2SO4 is 132.14 g/mol. The molar mass of hydrogen is 1.008 g/mol. Therefore, the percentage by mass of hydrogen in (NH4)2SO4 is (8 × 1.008) / 132.14 * 100 ≈ 6.09%.
A 83.6 g sample of an unknown compound contains 19.4 g of hydrogen What is the percent by mass of hydrogen in the compound?
To calculate the percent by mass of hydrogen in the compound, you need to divide the mass of hydrogen by the total mass of the compound and then multiply by 100. Percentage mass of hydrogen = (19.4 g / 83.6 g) x 100 ≈ 23.2% hydrogen mass in the compound.
What percentage of water is hydrogen?
By mole, water is 66.666r% hydrogen but by mass it is about 11.9% hydrogen.
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 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 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 percentage by the mass of hydrogen in (NH4)2SO4?
The molar mass of (NH4)2SO4 is 132.14 g/mol. The molar mass of hydrogen is 1.008 g/mol. Therefore, the percentage by mass of hydrogen in (NH4)2SO4 is (8 × 1.008) / 132.14 * 100 ≈ 6.09%.

Percentage by mass of components of water?
11% Hydrogen and 89% Oxygen
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 percentage of hydrogen in hydrogen Bromide?
It all depends on what you're looking for. If you mean ratio of atoms, It is a one:one ratio, so 50% each If you mean mass, 1.0125% of the mass of one molecule is hydrogen and the other 98.9875% is bromine.
Which isotopes of hydrogen has more mass percentage?
Protium, the most common isotope of hydrogen with one proton and no neutrons, has a higher mass percentage compared to deuterium and tritium, which have one proton and one and two neutrons respectively. This is because the extra neutrons in deuterium and tritium add to their mass, resulting in lower mass percentages.
