Mass of KNO3
K = 1 * 39.10 g = 39.10 g
N = 1 * 14.01 g = 14.01 g
O = 3 * 16.00 g = 48.00 g
Total = 101.11 g
The molar mass of potassium nitrate is 101.11 grams.
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 chemical formula KNO3 is for potassium nitrate.
The chemical formula for saltpeter is KNO3, which represents potassium nitrate.
The gram formula mass of acetic acid (CH3COOH) is approximately 60.05 g/mol.
The mass of a mole of an ionic compound.
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 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).
Get moles by; Molarity = moles of solute/Liters of solution 0.50 M KNO3 = moles KNO3/2.0 L = 1.0 mole KNO3 Now find grams of 1.0 mole KNO3 1.0 mole KNO3 (101.11 grams/1 mole KNO3) = 101.11 grams KNO3 needed call it 100 grams
The chemical formula for potassium nitrate is KNO3.
