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.
The gram formula for potassium sulfite (K2SO3) is 158.27 g/mol.
H2O's molar mass is 18 g/mol.
The gram formula mass of sodium (Na) is approximately 23 grams per mole.
The gram formula mass of acetic acid (CH3COOH) is approximately 60.05 g/mol.
To determine the molecular formula from the empirical formula and gram formula mass, first calculate the empirical formula mass of C4H9 (4 carbons + 9 hydrogens). Then, divide the gram formula mass by the empirical formula mass to find the ratio. Finally, multiply the subscripts in the empirical formula by this ratio to get the molecular formula, which in this case is C8H18.
The gram formula for potassium sulfite (K2SO3) is 158.27 g/mol.
The formula of sodium fluoride is NaF; its gram formula mass is 41.9882.
H2O's molar mass is 18 g/mol.
The gram formula mass of sodium (Na) is approximately 23 grams per mole.
The mass of a mole of an ionic compound.

The gram-formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit of the compound. For NO2, the gram-formula mass is calculated by adding the atomic mass of nitrogen (N) and two times the atomic mass of oxygen (O).
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
The formula mass of H2SO4 (Sulfuric acid) is calculated by adding up the atomic masses of each element in the compound. For H2SO4, it is 2 atoms of hydrogen (H), 1 atom of sulfur (S), and 4 atoms of oxygen (O). The atomic masses of H, S, and O are 1, 32.06, and 16, respectively. Therefore, the formula mass of H2SO4 = (21) + 32.06 + (416) = 98.08 grams/mol.
To convert one gram of H2SO4 to one ml, you need to know the density of H2SO4. The density of sulfuric acid (H2SO4) is approximately 1.84 g/ml, so one gram of H2SO4 is roughly equal to 1/1.84 = 0.5435 ml.
H2SO4 is the formula for sulfuric acid.
