There are 4 easy steps to find the molar mass of NaC7H5O2 based on its chemical formula. 1. Count The Number of Each Atom. The first step to finding the molar mass of Sodium Benzoate is to count the number of each atom present in a single molecule using the chemical formula, NaC7H5O2: 2.
Jan 18, 2024 · The general molar mass formula of a compound AxByCz involves multiplying the number of atoms by the molar mass of that element and adding the mass of all the elements in the molecule to get the molar mass: \mu = x \cdot \mu_\mathrm {A} + y \cdot \mu_\mathrm {B} + z \cdot \mu_\mathrm {C} μ = x ⋅ μA + y ⋅ μB + z ⋅ μC.

Chemical
Sodium benzoate will react with sodium hydroxide to produce benzene: 1. C6H5COONa + NaOH → C6H6 + Na2CO3 Small amounts of biphenyl and benzophenonewill also be produced as side products. Ascorbic acidwill also reduce the salt to benzene under certain conditions.
Physical
Sodium benzoate is a white hygroscopic compound, with a characteristic smell. It has a solubility in water of 62.7 g/100 ml at standard conditions. Sodium benzoate is also soluble in liquid ammonia and pyridine. It is poorly soluble in most alcohols, like methanol and ethanol.
Sodium benzoate can be prepared by reacting benzoic acidand sodium hydroxide, bicarbonate or carbonate.
Make benzoic acidMake benzoic acid estersSafety
Sodium benzoate has low toxicity to humans, and recent studies have shown to have some beneficial effects, in preventing Alzheimer and Parkinson's, though the results aren't conclusive so far. Cats however, have a significantly lower tolerance against benzoic acid and its salts, than rats and mice. If consumed with ascorbic acid, it may yield benzene, which is carcinogen, phenomenon observed in drinks containing sodium benzoate as preservative. However the levels of benzene obtained are extre...
Storage
Sodium benzoate should be stored in closed bottles, as it's slightly hygroscopic, though keeping it in a dry chamber is sufficient.
Disposal
Sodium benzoate has low toxicity and doesn't require special disposal. Discard it as you wish.

May 26, 2023 · Hence the Molar mass of Sodium benzoate (C7H5NaO2) is 144.105 g/mol. I hope you have understood the short and simple calculation for finding the molar mass of Sodium benzoate. Remember. In some books, you may see the unit of molar mass as grams/mole or g/mole. But all these units (i.e g/mol, grams/mole and g/mole) are the same.
molar mass = 22.99 g; Therefore, 1 mol Na = 22.99 g Na = 6.022 × 10 23 atoms Na. Answer B molar mass = 78.05 g; Therefore, 1 mol Na 2 S = 78.05 g Na 2 S = 6.022 × 10 23 formula units Na 2 S. Answer C molar mass = 44.02 g; Therefore, 1 mol N 2 O = 44.02 g N 2 O = 6.022 × 10 23 molecules N 2 O.
Aug 17, 2022 · Example #1: Find the Molar Mass of an Element. For example, find the mass of one mole of sodium. Do this by looking up sodium (Na) on the periodic table. The relative atomic mass is the same as the molar mass (except molar mass is in g/mol). The molar mass of sodium is 22.99 g/mol.
