How to solve the questions of moles in chemistry?

Answers

Answered by priyambaksi

first you need to balance any equation given. then you need to figure the mole ratios.say 2 moles of iron (II) sulfide form 1 mole of iron (II) chloride, then it is a 2 to 1 ratio, then you say you have~ 1 mole of iron sulfide X 2 moles of iron chloride/1mole of iron sulfide X of iron sulfide/1 mole of iron sulfide. Just make sure to start with a balanced equation.

there is a formula which is importent : (n) moles = (m) mass / (M)molar mass

Rajanverma: How to solve with avatar no.

Rajanverma: Sorry avagardo

Rajanverma: Thanks bro

priyambaksi: Avogadros number is the number of molecules in one mole. You would use Avagadros number for calculating a mass if you new you had a mole of something (that means Avagadros number of different particles) and you knew the mass of those particles. The avogrado number is 6.0221415×10^23.

Rajanverma: Ok I got it.

Rajanverma: Sir the answer given by her is different

Rajanverma: Thanx sir

USE THE AVAGARDO NUMBER 6.022 * 10(23)

priyambaksi: you should apologize bro to her. look at his profile she is much better answer giver them me. don't underestimate her.

vishakha: its okay....

vishakha: :)
