How do you determine the gram mass of an element in a molecule if you know the gram mass for the molecule and its molecular weight?
To determine the gram mass of an element in a molecule, you first need to know the molecular formula of the molecule, which indicates the number of each type of atom present. Calculate the molar mass of the entire molecule based on the atomic weights of its constituent elements. Then, find the molar mass contribution of the specific element by multiplying its atomic weight by the number of atoms of that element in the formula. Finally, use the ratio of the element's molar mass to the total molar mass of the molecule and multiply by the total gram mass of the molecule to find the gram mass of the element.
Difference between Gram atom and gram molecule?
It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
What is the gram molecular mass of phosphorous?
The atomic mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.

What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
What is the gram molecular mass of phosphorous?
The atomic mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
What is a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
What is the mass gram of one molecule of caffeine CaH10N4o2?
The molecular mass of caffeine (C8H10N4O2) is approximately 194.19 g/mol. Therefore, the mass of one molecule of caffeine is 194.19 g/mol in grams.
What is the gram molecular mass of H2SO4?
The gram molecular mass of H2SO4 is approximately 98 grams per mole. This is calculated by adding up the atomic masses of the elements in the compound: 2 hydrogen atoms (2 g/mol), 1 sulfur atom (32 g/mol), and 4 oxygen atoms (64 g/mol).
How many moles of sulfur are present in a 16-g sample of sulfur?
To determine the number of moles of sulfur in a 16-g sample, you need to divide the mass by the molar mass of sulfur. The molar mass of sulfur is approximately 32 g/mol. Thus, 16 g/32 g/mol = 0.5 moles of sulfur in the sample.
When 1 gram of sulfur is burnt the mass of the product formed will be?
when a gram of sulfur is burnt the mass product formed will be more than 1gram,zero,less than 1 gram or equal to 1 gram.
What is the gram formula mass of H2SO4?
The relative atomic masses of sulfur, oxygen and hydrogen are 32, 16 and 1 respectively. The molecular formula of sulfuric acid is H2SO4. Therefore, sulfuric acid has a mass number of 98 g/mol.
