What the structure of a molecule have a molecular weight of 22?
A molecule weighing 22 units can be constructed with one atom of carbon and four atoms of hydrogen. This is a methane molecule that normally would weigh 16 units. However, if two hydrogens are deuterium (2 units each) and two atoms of hydrogen are tritium (3 units each), the molecular weight comes out to 22 units.
What shape would a molecule of hydrogen sulfide have?
A molecule of hydrogen sulfide (H2S) would have a bent shape due to its molecular geometry. It consists of two hydrogen atoms bonded to a sulfur atom with lone pairs of electrons around the sulfur, causing the molecule to bend.
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Is C8H16O8 molecular?
No, C8H16O8 is not a single molecule. It represents the chemical formula for a carbohydrate or sugar compound with 8 carbon, 16 hydrogen, and 8 oxygen atoms. Each molecule of this compound would have this ratio of atoms.
How would we determine the molecular weight for a molecule water h2o?
To determine the molecular weight of a molecule like water (H2O), you would add up the atomic weights of all the atoms in the molecule. For water, you would add the atomic weight of two hydrogen atoms and one oxygen atom, which gives you a molecular weight of approximately 18.015 atomic mass units (amu).

How many atoms of hydrogen are in one molecule?
I am assuming you are wondering how many atoms of hydrogen are in molecular hydrogen (H2), then the answer would be two since molecular hydrogen is always found as a diatomic species in nature. Similar to oxygen (O2) which is also naturally diatomic.
What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
What is the size of acetone molecule?
The acetone molecule has a molecular weight of 58.08 g/mol and a molecular formula of C3H6O, which consists of 3 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom. The actual size of the molecule would depend on its structure and arrangement of atoms in its three-dimensional space.
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
What percent of hydrogen in hydrogen peroxide?
The formula is H2O2 so in pure hydrogen peroxide it would be 50 mole %. As the molecular weight is 34 it would be 2/34 x 100 = 5.9 weight % (1 decimal place).
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Is there a molecule with a mass of 1.78 gM?
No. The lightest element is hydrogen at 1.008 g/mole. Molecular hydrogen, H2, would therefore be 2.016 g/mole. There can't be anything in between.
How many grams of hydrogen are in 46g of CH4O?
To calculate the grams of hydrogen in CH4O, we need to consider the molecular formula CH4O. In this formula, there are 4 hydrogen atoms. Since the molecular weight of hydrogen is approximately 1 g/mol, the total grams of hydrogen in 46g of CH4O would be 4 grams.
What is equivalent weight of benzene?
The molecular weight of benzene is 78. Its equivalent weight is the molecular weight divided by the functionality. It depends on the reaction what the functionality is. Assuming it is reacting with chlorine and UV light, the functionality is 6 so the equivalent weight would be 78/6 = 13. If it was involved in a reaction involving the double bonds, there are 3 of them and the equivalent weight would be 78/3 = 26.
