The molecular formula =C₆H₁₂O₆

<h3>Further explanation</h3>

Given

6.00 g of a certain compound X

The molecular molar mass of 180. g/mol

CO₂=8.8 g

H₂O=3.6 g

Required

The molecular formula

Solution

mass C in CO₂ :

= 1.12/44 x 8.8

= 2.4 g

mass H in H₂O :

= 2.1/18 x 3.6

= 0.4 g

Mass O in compound :

= 6-(2.4+0.4)

= 3.2 g

Mol ratio C : H : O

= 2.4/12 : 0.4/1 : 3.2/16

= 0.2 : 0.4 : 0.2

= 1 : 2 : 1

The empirical formula : CH₂O

(CH₂O)n=180 g/mol

(12+2+16)n=180

(30)n=180

n=6

(CH₂O)₆=C₆H₁₂O₆

From the diagram,

(1) Liquid⇒Solid (Freezing)

Freezing: This is the process by through which a substance change from liquid to solid.

(2) Solid⇒Liquid (Melting)

Melting: This is a process through which a substance change from solid to liquid

(3) Liquid⇒gas (Evaporation)

Evaporation: This is a process through which a substance change from liquid to gas.

(4) gas⇒Liquid (Condensation)

Condensation: This is a process through which a substance change from gas to liquid

(5) Solid⇒gas (Sublimation)

Sublimation: this is a process through which a subtance change from solid to gas

(6) gas⇒solid (Deposition)

Deposition: This is a process through which gas transform into solid.
