So when dealing with molar mass when do you know to round up

1 answer:

8 0

The first rule is to use four digits in atomic weights and consider the calculated formula or molar mass as given with four significant digits. This rule is appropriate for beginners but has some disadvantages.

The second rule is to use all digits in the recommended atomic weights and to estimate the accuracy of the result from the number of decimal places or significant digits in these.

The third rule is to use all digits in the recommended atomic weights and to calculate the absolute maximum uncertainty of the result from the recommended uncertainties of the atomic weights. The uncertainty is rounded up to one (two) significant digit(s), and the formula or molar mass is rounded to the same absolute accuracy as the rounded uncertainty.

Draw the organic product formed when the following compounds undergo a substitution reaction: (c) ethanoic acid and diethylamine

djyliett [7]

The organic product formed when the ethanoic acid and diethylamine compounds undergo a substitution reaction is N, N- diethyl ethanamide.

<h3>What is Substitution reaction? </h3>

Substitution reaction is a reaction in which one group substitute the functional group of another organic compound or it can also be defined as a reaction that involves the replacement of one atom or group of atoms of a compound with another atom or group of atom.

<h3>Types of Substitution reaction</h3>

Substitution Reactions are basically of two types:

nucleophilic reaction and electrophilic reactions. These two types of substitution reactions differ in the types of atom that is attached to its original molecule. In the nucleophilic reactions, the atom is electron-rich species, on the other hand, in the electrophilic reaction, the atom is an electron-deficient species.

Thus, we concluded that the organic product formed when the ethanoic acid and diethylamine compounds undergo a substitution reaction is N, N- diethyl ethanamide.
