How many particles are there in 0.1 mole potassium iodide, KI, and hydrogen peroxide H2O2, and how did you work that out?

Thank you in advance

there are 6.0221415 × 10^23 particles in 1 mole of anything. so for 0.1 moles you just time avagadro's constant by 0.1

Oh right ok, so I don't have to multiply 6.02 x 10^23 for every atom in the molecule? So say for H2O2, I wouldn't have to do the following calculation:

6.02 x 10^23 x 4 (2 H, 2 O) = Ans

Ans * 0.1= ?

You have an odd sense of humour.

the formula for the molecule isn't important. The definition of a mole is 6.0221415 × 10^23 molecules. So 0.1 mole of anything will contain 6.0221415 × 10^22 molecules.
