What Makes up 75 percent of the sun's mass?
Hydrogen. Actually the figure is closer to73.46% hydrogen. 24.85% is helium.
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 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 the mass number for hydrogen?
the relative atomic mass for hydrogen is 1.0079 amu.
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.
If a hydrogen atom has a mass of 3 is it an isotope?
No, a hydrogen atom with a mass of 3 is not an isotope of hydrogen. Hydrogen isotopes include protium (mass 1), deuterium (mass 2), and tritium (mass 3).
What is the mass of an hydrogen atom?
The atomic mass of Hydrogen is 1.00794 amu.
What is the mass of a hydrogen nucleus?
The mass of a hydrogen nucleus is approximately 1 atomic mass unit.
Water its 11.2 percent by mass hydrogen How many kilograms of water would contain 5.0 grams of hydrogen?
To find the mass of water containing 5.0 grams of hydrogen, we need to set up a proportion using the mass percentage of hydrogen in water. Since water is 11.2% hydrogen by mass, we can calculate the mass of water using the formula: (5.0 grams of hydrogen) / (11.2 grams of hydrogen per 100 grams of water) = x grams of water. Converting grams to kilograms, the mass of water containing 5.0 grams of hydrogen would be 5.0 g / 11.2% = 44.64 g. This figure converted to kilograms is 0.04464 kg.
What is the mass number of hydrogen?
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
How many grams of hydrogen are there in 16 grams of methane gas?
First you need atomic masses. Then you need to add them up to find the molecular mass of methane (CH4).Carbon = 12.0 gramsHydrogen = 1.0×4 = 4.0 grams--------------------------------------Methane = 16.0 gramsNow that you know the total mass, you can figure out how much of the compound is actually hydrogen (by percent). So you take the mass of hydrogen and divide it by the total mass of methane.4.0 ÷ 16.0 = .25 = 25% of methane is hydrogenNow we take the 16 grams and figure out how much of that 16 grams is hydrogen. We know that 25% of it is hydrogen, so take one-fourth of 16 to get 4. But sometimes the numbers aren't as easy and you have to multiply them out.25% of 16 = .25 × 16 = 4 grams hydrogen
