Explanation: Diluting a solution means adding more solvent, usually water, meaning that there is less solute in any sample of the solution. Adding more solvent means that the volume of the solution will increase.

Determine the molecular formula for the following hydrocarbons: a. Hexane b. Methane c. Propyne d. 1-pentene e. 2-octyne f. Deca

kirill [66]

Answer: The molecular formulas are written below.

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula for these hydrocarbons is $C_nH_{2n+2}$

These hydrocarbons have the name ending with the suffix '-ane'

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is $C_nH_{2n}$ and $C_nH_{2n-2}$

The hydrocarbons having double and triple bonds have the name ending with the suffix '-ene' and '-yne' respectively.

For the given options:

Option a: Hexane

'Hex' prefix is added for the chain having 6-Carbon atoms. So, the formula for this saturated hydrocarbon is $C_6H_{(2\times 6)+2}=C_6H_{14}$

Option b: Methane

'Meth' prefix is added for the chain having 1-Carbon atom. So, the formula for this saturated hydrocarbon is $C_1H_{(2\times 1)+2}=CH_{4}$

Option c: Propyne

'Prop' prefix is added for the chain having 3-Carbon atoms. So, the formula for this unsaturated hydrocarbon is $C_3H_{(2\times 3)-2}=C_3H_4$

Option d: 1-pentene

'Pent' prefix is added for the chain having 5-Carbon atoms. So, the formula for this unsaturated hydrocarbon is $C_5H_{(2\times 5)}=C_5H_{10}$ . The double bond is present between C-1 and C-2 atoms

Option e: Octyne

'Oct' prefix is added for the chain having 8-Carbon atoms. So, the formula for this unsaturated hydrocarbon is $C_8H_{(2\times 8)-2}=C_8H_{14}$

Option f: Decane

'Dec' prefix is added for the chain having 10-Carbon atoms. So, the formula for this saturated hydrocarbon is $C_{10}H_{(2\times 10)+2}=C_{10}H_{22}$

Option g: Heptane

'Hept' prefix is added for the chain having 7-Carbon atoms. So, the formula for this saturated hydrocarbon is $C_7H_{(2\times 7)+2}=C_7H_{16}$

Option h: 4-nonene

'Nona' prefix is added for the chain having 9-Carbon atoms. So, the formula for this unsaturated hydrocarbon is $C_9H_{(2\times 9)}=C_9H_{18}$ . The double bond is present between C-4 and C-5 atoms

A sample of gas has a mass of 827 mg . Its volume is 0.270 L at a temperature of 88 ∘ C and a pressure of 975 mmHg . Find its mo

avanturin [10]

Steps:

Mw = w * R * T / p * V

T = 88 + 273 => 361 K

p = 975 mmHg in atm :

1 atm = 760 mmHg

975 mmg / 760 mmHg => 1.28 atm

Therefore:

= 0.827 * 0.0821 * 361 / 1.28 * 0.270

= 24.51 / 0.3456

molar mass = 70.92 g/mol
