What is the gram molecular mass of hydrogen?
The gram molecular mass of H2 is 2g.
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.
How the moleculer formula of a compound is calculated if its emperical formula is known?
The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.
What is the gram molecular mass of H2SO4?
The relative molecular mass of sulfate ion is 96. Sulfuric acid molecule has two protons attached to it. Therefore the GMM of sulfuric acid is 98g.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
How many moles of sulfur are present in a 16-g sample of sulfur?
No. of moles=given mass/gram molecular mass =16/16 =1
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 hydrogen?
The gram molecular mass of H2 is 2g.
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 a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.

A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?
The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
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 gram atomic mass of sulfur?
32.065
What is the molar mass of so2?
The molecular mass of sulfur dioxide is 64,07.
