The empirical formula of a compound containing carbon, hydrogen, and chlorine is C2HCl. The molar mass of this compound is 120.98 g/mol. What is its molecular formula? If an organic compound has a molecular formula of C5H10 and the mass of its empirical formula is 12 g, determi...
molecular weight- (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule relative molecular mass mass- the property of a body that causes it to have weight in a gravitational field chemical science,chemistry- the science of matter; the branch of the natural ...
For this we must know the molar mass of each atom in the molecular formula. Answer and Explanation: Given molar mass = 88 g/mol Now we will find the molecular mass of the following molecular formula and for this we must the following molar......
The chemical formula of a compound is a symbolic representation of its chemical composition. Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the ...
In all cases, we used the following formula for coordination number (Eq. 1, see below): $${{CN}}_{{ij}}=\frac{1-{(\frac{{r}_{{ij}}}{{r}_{0}})}^{n}}{1-{(\frac{{r}_{{ij}}}{{r}_{0}})}^{m}}$$ (1) Where CNij is the coordination number between atoms i ...

Weakly ionized, radio-frequency, glow-discharge plasmas formed from methyl ether or the vapors of a series of dimethyl oligo(ethylene glycol) precursors (general formula: H-(CH 2 OCH 2 ) n -H; n =1 to 4) were used to deposit organic thin films on polytetrafluoroethylene. X-ray photo...
At the end of crystallization, the hydrolysis of DMF stops together with the stabilization of pH. The main non-crystalline by-product of MIL-53 synthesis is a mixture of soluble dimethylammonium salts with brutto-formula [((CH3)2NH2)x(NO3)x-1]+[NO3]−. Method development and outlook ...
Flavors are considered among the most valuable ingredients in any formula. However, aromatic substances are volatile and can be lost during processing and storage. Thus, it is beneficial to develop strategies for their retention in formulations. The aim of the present study was to evaluate the abi...
