Question

Відносна густина алкану за метаном 3,625. Визначте, який це алкан. У відповідь запишіть назву цього вуглеводню.

Answer 1

Ответ:

C4H10 (бутан или 2-метилпропан)

Объяснение:

mr=3.625*16=58

CxH2X+2=58

12X+2X=56

X=4

C4H10

Answer 2

Relative Density of Alkanes

The relative density of an alkane is a measure of its density compared to the density of water. It is also known as specific gravity. The relative density of an alkane can provide information about its molecular structure and composition.

Calculation of Relative Density The relative density of an alkane can be calculated using the formula: Relative Density = Density of Alkane / Density of Water

Calculation for the Given Relative Density

Given that the relative density of the alkane in question is 3.625, we can determine the specific alkane based on this value.

Identifying the Alkane

To identify the alkane with a relative density of 3.625, we can refer to the densities of various alkanes and their corresponding relative densities.

Based on the provided relative density, the alkane with a relative density of 3.625 is propane.

Therefore, the alkane with a relative density of 3.625 is propane.
