Question

How many molecules of SrCrO4 are in a sample of SrCrO4 0.556 moles?

Answer 1

`3.35*10^(23)\ SrCrO_4\ molecules`

Step-by-step explanation:

`We\ are\ given\ that,\\No.\ of\ moles\ of\ SrCrO_4=0.556\\Hence,\\As\ we\ know\ that,\\No.\ of\ particles=Avagadro's\ Constant*No.\ of\ moles\\We\ already\ know\ that\ Avagadro's\ Constant=6.022*10^(23)\\Here,\\No.\ of\ SrCrO_4\ molecules= 6.022*10^(23)*0.556\\Hence,\\No.\ of\ SrCrO_4\ molecules=3.348*10^(23) molecules\ \approx 3.35*10^(23)\ SrCrO_4\ molecules`
