Mehato ea ho Fumana Foromo ea Molek'hule
Ho fumana foromo ea limolek'hule, re hloka boima ba molar ba motsoako le foromo ea oona ea boiphihlelo. Mehato e akaretsang ke ena:
1. Fumana Foromo ea Boqapi: Etsa mehato ea ho fumana foromo ea boqapi pele.
2. Ho Bala Bongata ba Molar ba Foromo ya Empirical: Kenya bongata ba molar ba karolo e nngwe le e nngwe foromong ya empirical ho fumana boima ba molar ba foromo ya empirical.
3. Ho Fumana Bongata ba Molumo ba Motsoako: Hangata ho fanoa ka lipotso kapa liteko.
4. Ho Fumana N Factor: Arola boima ba mole ba motsoako ka boima ba molar ba foromo ea empirical ho fumana factor (n).
5. Ho Fumana Foromo ea Molek'hule: Atisa ntlha (n) ka lingoloa tsohle tse foromong ea 'mele ho fumana foromo ea molek'hule.
Lipotso tsa Mehlala le Puisano
Potso ea 1: Ho Fumana Foromo ea Bohlale
Motswako o na le sebopeho se latelang sa boima: 40% ya khabone (C), 6,7% ya haeterojene (H), le 53,3% ya oksijene (O). Fumana foromo ya teko ya motswako ona.
Karabo:
1. Fetolela 'Misa ho ba Moles:
– Khabone:
\[
\frac{40 \text{ g}}{12 \text{ g/mol}} = 3,33 \text{ mol}
\]
– Haedrojene:
\[
\frac{6,7 \text{ g}}{1 \text{ g/mol}} = 6,7 \text{ mol}
\]
– Oksijene:
\[
\frac{53,3 \text{ g}}{16 \text{ g/mol}} = 3,33 \text{ mol}
\]
2. Ho Fumana Karolelano ea Mole:
– C: 3,33 mol / 3,33 = 1
– H: 6,7 mol / 3,33 = 2
– O: 3,33 mol / 3,33 = 1
3. Ho Ngola Mekhoa ea Boqapi:
– Karolelano ea limolek'hule tsa C:H:O ke 1:2:1, kahoo foromo ea empirical ke CH₂O.
Potso ea 2: Ho Fumana Foromo ea Molek'hule
Haeba boima ba molar ba motsoako o nang le foromo ea empirical CH₂O bo tsejoa e le ligrama tse 180/mol, fumana foromo ea eona ea limolek'hule.
Karabo:
1. Boima ba molar ba foromo ea 'mele CH₂O:
– Boima ba molar C = 12 g/mol
– Boima ba molar H = (2 x 1) g/mol = 2 g/mol
– Boima ba molar ba O = 16 g/mol
Kahoo boima ba molar ba CH₂O = 12 + 2 + 16 = 30 g/mol
2. Fumana ntlha ea n:
\[
\frac{boima \text{ molar}}{boima \text{ empirical molar}} = \frac{180 \text{ g/mol}}{30 \text{ g/mol}} = 6
\]
3. Ho Fumana Foromo ea Limolek'hule:
– N factor ke 6, kahoo foromo ea limolek'hule ke 6 x (CH₂O) = C₆H₁₂O₆.
Mehlala ea lipotso tse hlokang lipalo tse rarahaneng haholoanyane
Potso ea 3: Ho Fumana Foromo ea Boiphihlelo ho tsoa ho Lintlha tsa Peresente
Motswako wa tlhaho o na le 75.0% ya khabone, 20.0% ya haeterojene, le 5.0% ya naetrojene. Fumana foromo ya tlhahlobo ya motsoako.
Karabo:
1. Fetolela 'Misa ho ba Moles:
– Khabone:
\[
\frac{75.0 \text{ g}}{12.0 \text{ g/mol}} = 6.25 \text{ mol}
\]
– Haedrojene:
\[
\frac{20.0 \text{ g}}{1.0 \text{ g/mol}} = 20.0 \text{ mol}
\]
– Naetrojene:
\[
\frac{5.0 \text{ g}}{14.0 \text{ g/mol}} = 0.357 \text{ mol}
\]
2. Ho Fumana Karolelano ea Mole:
– C: 6.25 mol / 0.357 = 17.5 ≈ 18
– H: 20.0 mol / 0.357 = 56 ≈ 56
– N: 0.357 mol / 0.357 = 1
3. Ho Ngola Mekhoa ea Boqapi:
– Karolelano ea mole C:H:N ≈ 18:56:1, foromo ea 'nete ke C₁₈H₅₆N.
Qetello
Ho utloisisa likhopolo tsa liforomo tsa limolek'hule le tsa boiphihlelo ho bohlokoa k'hemistri. Ka ho latela mehato e hlalositsoeng le ho itloaetsa mehlala e fanoeng, re tšepa hore u tla ba le boiphihlelo bo eketsehileng ba ho fumana liforomo tsa boiphihlelo le tsa limolek'hule tsa metsoako. Itloaetse khafetsa ho tebisa kutloisiso ea hau ea thepa ena.
