1.1. Topshiriqni bajarish uchun misol

Misol. Normal sharoitda quyidagi parametrlarga ega daraxtni o'stirish uchun qancha hajmda o'simlik karbonat angidrid gazini o'zlashtirishi kerak: daraxt diametri D = 0,8 m, balandligi h = 15 m, yog'och zichligi ρ = 0,08 m³.

Biz barcha yog'ochni ugleroddan tayyorlangan va daraxt tanasi silindrsimon shaklga ega deb taxmin qilamiz.

Hisoblash: Daraxtning massasini (m) aniqlaymiz. Buning uchun ko’ndalang kesimi (πr²), balandligi (h) (r radius D/2=0,4m), va zichlikni (ρ) ko'paytiramiz.

Ya'ni,

yoki (1.1)

Karbonat angidriddan o'tin hosil bo'lishi reaktsiysi qo’yidagicha davom etadi:

(1.2)

Biz (1.2) tenglamadagi karbonat angidridning (CO₂) massasini m₁ ga, uglerodning massasini (C) m₂ ga va ularning molekulyar og'irliklarini M₁ va M₂ ga mos ravishda teng deb qabul qilamiz.

Reaksiya beruvchi moddalar massalari va ularning molekulyar massalarining nisbatidan foydalanamiz:

(1.3)

bu erda m₁ va m₂ - reaktivlarning massalari; M₁ va M₂ ularning molekulyar og'irliklari; k₁ va k₂ ularning stexiometrik koeffitsientlari ((1.2) tenglama bo'yicha ular biriga teng).

Kislorodning atom massasi 16 ga, uglerod – 12 gateng (D.I.Mendeleyev jadvalidan). Shunga ko'ra, CO₂ (M₁) ning molekulyar og'irligi 16×2+12=44; uglerodning molekulyar massasi uning atom massasiga teng olinadi, ya'ni. M₂=2. (1.3) formuladan foydalanib quyidagilarga erishamiz:

(1.4)

Ma'lumotlarni almashtirib, quyidagilarni olamiz:

Ma'lumki, normal sharoitda 1 molga teyg har qanday gaz 22,4 litr hajmni egallaydi. 1 mol karbonat angidridning massasi 0,044 kg yoki 44 g (bir molning massasi son jihatdan molekulyar og'irlikka teng bo'lgani uchun) bo'lgani uchun, 2200 kg tarkibidagi karbonat angidrid mollari sonini 22,4 litrga ko'paytirsak, biz kerakli qiymatni olamiz.

.

Javob: normal sharoitda olingan karbonat angidrid hajmi 1120m³.
