Categorize each hydrocarbon as being saturated or unsaturated.
Bond [772]

Answer :

Saturated hydrocarbon : 3-methyloctane, propane, heptane.

Unsaturated hydrocarbon : cyclopentene, heptyne

Explanation :

Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.

For example : Methane, Ethane, etc.

Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds.

For example : Ethene, Butyne, etc.

Therefore, the saturated and unsaturated hydrocarbons are:

Saturated hydrocarbon : 3-methyloctane, propane, heptane.

Unsaturated hydrocarbon : cyclopentene, heptyne

A 1.25 g gas sample occupies 663 ml at 25∘ c and 1.00 atm. what is the molar mass of the gas?
lakkis [162]

Using ideal gas equation,  

P\times V=n\times R\times T

Here,  

P denotes pressure  

V denotes volume  

n denotes number of moles of gas  

R denotes gas constant  

T denotes temperature  

The values at STP will be:  

P=1 atm  

T=25 C+273 K =298.15K

V=663 ml=0.663L

R=0.0821 atm L mol ⁻¹

Mass of gas given=1.25 g g

Molar mass of gas given=?

Number of moles of gas, n= \frac{Given mass of the gas}{Molar mass of the gas}

Number of moles of gas, n= \frac{1.25}{Molar mass of the gas}

Putting all the values in the above equation,

1\times 0.663=\frac{1.25}{Molar mass of the gas}\times 0.0821\times 298.15

Molar mass of the gas=46.15
