Mole Se Mass Aur Particles | Class 9 Chemistry Unit 1.5 | Char Arrows Mein Poora Topic

Poora topic sirf ek tasveer par khara hai. Teen dabbe: mass, mole, particles. Aur ek baat jo sab kuch asaan kar deti hai: mass se particles tak koi seedha raasta hai hi nahi. Darmiyan mein hamesha mole aata hai. To seekhna sirf do safar hai. Mass se mole, aur mole se particles. Baqi sab in ka combination hai. Pehla safar: molar mass, aur wo formula jo mass ko moles mein badal deta hai. Book ka apna sawal, sixty gram carbon dioxide, ek ek operation kar ke. Aur ek baat jo book nahi kehti aur student ko chahiye: jawab poora number na ho to bhi bilkul theek hai. Doosra safar: mole se particles. Aur us mein wo chhoti si tarkeeb jo darawne hisaab ko do digit ki division bana deti hai. Ten to the power twenty three dono numbers mein maujood hai, is liye wo cancel ho jata hai. Aakhir mein wheel. Mass, mole aur particles ek ring par, char arrows ke saath. Jis taraf ja rahe hain, usi se tay hota hai ke multiply karna hai ya divide. Char formulas yaad karne ki zaroorat khatam. Aur is ke saath chapter ki parhai mukammal. Agle videos mein exercise. Definitions aur formulas English mein hain, bilkul un alfaaz mein jo paper maangta hai. Samajh Urdu mein hai.
