How do you calculate formula weight in grams?
The actual formula for calculating the Gram Molecular Mass of a substance is : Gram Formula Mass = mass of the solute/formula mass of the solute. It is always expressed in the unit grams/mole (g/mol).
What is C17H35COOH?
Stearic acid having IUPAC name octadecanoic acid is a saturated fatty acid. its chemical formula is C17H35COOH. Palmitic acid is the most common saturated fatty acid found in plants, animals and microorganisms and hexadecanoic acid in IUPAC nomenclature.
What is the density of stearic acid in G cm3?
2. Stearic acid, C,H3COOH, has a density of 0.85 g/cm. The molecule occupies an area of 0.205 nm in a closed-packed surface, film.
How many atoms are in stearic acid?
“…Stearic acid (systematic name, octadecanoic acid, CH3(CH2)16COOH) is a long-chain fatty acid consisting of 18 carbon atoms without double bonds.
How do you find the formula mass?
To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons).
What is gram mass?
Gram molecular mass is equal to the molecular weight of a substance or the sum of all the atomic masses in its molecular formula. It is equal to molecular mass of a molecule in grams. For example; Gram molecular weight of carbon dioxide (CO2) is : 12+(2×16)

What is meant by formula mass?
The formula mass of a substance is defined as the sum of the atomic masses of constituent atoms in an ionic compound. This is generally used for ionic compounds which do not contain discrete molecules, but ions as their constituent units.
What is formula mass example?
Formula Mass for Ionic Compounds As an example, consider sodium chloride, NaCl, the chemical name for common table salt. Sodium chloride is an ionic compound composed of sodium cations, Na+, and chloride anions, Cl−, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (see [link]).
What is the molar mass of sodium stearate?
306.46 g/molSodium stearate / Molar mass
How do you find how many grams are in a mole?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How do I calculate formula mass?
To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
How do you calculate mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
What is the formula of mass and weight?
Mass and weight are related by the equation Weight = mass x gravity. You might know this equation as Newton’s II Law of Motion Force = mass x acceleration (F = ma) where Force (or weight) is measure in Newtons, N, and the mass is measured in kilograms, kg.
Why does stearic acid have a high melting point?
Why does stearic acid have a high melting point? The reason for the higher melting point of stearic acid as compared to octadecane is the fact that -COOH group is able to engage in inter-molecular “hydrogen bonding”. Click to see full answer. Also to know is, what is the melting point of stearic acid? 69.3 °C.
What is the density if stearic acid?
Stearic acid is used as a negative plate additive in the manufacture of lead-acid batteries. It is added at the rate of 0.6 g per kg of the oxide while preparing the paste. It is believed to enhance the hydrophobicity of the negative plate, particularly during dry-charging process.
Which acid is more strong stearic acid or citric acid?
Stearic acid is used as a thicken and stabilizer, citric acid is usually used to bring down ph Not open for further replies.
What is the size of stearic acid molecule?
This works out at 0.00001/50 cm or 20 Å which appears to be the length of a stearic acid molecule. Stearic acid has a carbon chain structure and an acidic group linked to one end. When the experiment is repeated using molecules one carbon atom longer, the same volume of acid spreads over the same area and the layer is about 1.5 Å thicker.
