Monosodium glutamate (msg), a flavor enhancer, has been blamed for "chinese restaurant syndrome," the symptoms of which are headaches and chest pains. msg has the following composition by mass: 35.51 percent c, 4.77 percent h, 37.85 percent o, 8.29 percent n, and 13.60 percent na. what is its molecular formula if its molar mass is about 169 g?

The molecular formula of mono sodium glutamate is

Explanation:

Molar mass of sodium glutamate,M = 169 g/mol

let the molecular formula be

Percentage of carbon in the M.S.G. =35.52 %

a = 5

Percentage of Hydrogen in the M.S.G. = 4.77 %

b = 8

Percentage of oxygen in the M.S.G. =37.85 %

c = 3.99 ≈ 4

Percentage of nitrogen in the M.S.G. = 8.29 %

d = 1

Percentage of sodium in the M.S.G. =13.60 %

e = 0.99 ≈ 1

The molecular formula be :

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
