What is the gram molecular mass of sulfur molecule?
The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.
What is the molar mass of an element what are its units?
The molar mass of an element is the mass of one mole of atoms of that element, typically expressed in grams per mole (g/mol). It is numerically equivalent to the atomic mass of the element, which is found on the periodic table, but is specifically expressed in terms of mass per mole. For example, the molar mass of carbon is approximately 12.01 g/mol.
How you calculate atomic mass unit?
Step 1: Write out the chemical formula of the compound whose atomic mass you want to calculate. The chemical formula provides the number of atoms in one molecule of a compound (i.e. the chemical formula for water is H2O). For example, the chemical formula of phosphate is H3O4P.Step 2: Look up the atomic mass for each individual element in the given compound on the periodic table. This number is commonly found just below the letter symbol for the element. For our example, the atomic mass of hydrogen (H) is 1.008 amu per atom, oxygen (O) is 16.00 amu per atom and phosphorous (P) is 30.97 amu per atom.Step 3: Multiply the result for every atom in Step 2 by the number of atoms in one molecule of the compound. Phosphate contains three atoms of hydrogen, four atoms of oxygen and one atom of phosphorous in one molecule. So for phosphate the calculations would be as follows; 1.008 amu/atom x 3 hydrogen atoms per molecule = 3.024 amu of hydrogen per molecule, 16.00 amu/atom x 4 oxygen atoms per molecule = 64.00 amu of oxygen per molecule and 30.97 amu/atom x 1 phosphorous atom per molecule = 30.97 amu of phosphorous per molecule.Step 4: Add the numbers calculated for each atom in Step 3 together to determine the total amu for one molecule of the compound. So for phosphate the atomic mass is 3.024 + 64.00 + 30.97 = 97.99 amu in one molecule of phosphate.
The mass of a single TNT molecule?
The molar mass of TNT (Trinitrotoluene) is approximately 227.1 g/mol. This means that a single TNT molecule would have a mass of 227.1 g/mol (or 2.38 x 10^-22 grams per molecule).
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 physical properties would tell you about an element's mass per unit volume ratio?

How do you determine the molar mass of an element?
To determine the molar mass of an element, you sum the atomic masses of all the atoms in a molecule of that element. This involves finding the atomic mass of each individual element from the periodic table and adding them together based on the chemical formula. The unit for molar mass is grams per mole (g/mol).
What is the molar mass in grams of mole of an element equal to?
weight...'
What the molar mass for copper?
Atomic mass of Cu is 63.55 a.m.u. , 63.55 g/mole(Cu is an element, not a molecule)
What is the molar mass of a molecule that weighs 1 dalton per mole?
The molar mass of a molecule that weighs 1 dalton per mole is 1 gram per mole.
What is the gram molecular mass of sulfur molecule?
The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.
What is the atomic mass of the element in grams per mole (g/mol)?
The atomic mass of an element is the average mass of one atom of that element, measured in atomic mass units (amu). This value is also equivalent to the mass of one mole of atoms of that element, expressed in grams per mole (g/mol).
The molar mass of an element is equal to?
The element's average atomic mass.
The molar mass of an element is the mass of one?
The molar mass of an element is the mass of one mole of atoms of that element, measured in grams per mole. It is calculated by summing the atomic masses of the atoms in a chemical formula.

How do you calculate molecules to moles?
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
