Mavzuga doir ayrim masalalarni ishlanish usullari


1. Ayolning suyagi tarkibida jami 250 g tuz mavjud deb faraz qilsak, undagi kalsiy karbonat tuzining miqdorini g aniqlang.
A) 85,25 g B) 150 g C) 120 g D) 14,75 g


Ishlanishi:
1) Demak agar suyak tarkibida 250 g tuz mavjud bo’lsa, suyak tarkibida qancha kalsiy karbonat borligini aniqlab olamiz:
250 x 0,059 = 14,75 g CaCO₃ tuzi bor ekan chunki suyak tarkibida 5,9 % kalsiy karbonat tuzi mavjud.
