KIMYONING ASOSIY QONUNLARI
Mol miqdor


Molyar massa.Molekulyar massa.

Men doim qiyin testlarni dangasa va erinchoq o’quvchilarimga beraman chunki ular bu testlarni yechishni oson yo’lini topishadi
Agar bu dunyoda yaxshi yashashni istasang savdogar bo’l.
Agar u dunyoda yaxshi yashashni istasang ibodat qil.
Agar ikki dunyoda yaxshi yashashni istasang ilim o’rgan.
