10 μgmL-1 of n-octane in 10% acetone

Post by haku86 » Tue Jun 14, 2011 6:09 am

Need some help. How do I prepare this solution when the molecular weight of octane is 114.23 and acetone is 99%. I have prepared 10% acetone using m1v1=m2v2. Thanks :roll:

since you want 10 ug/ml of octane, you don't need the formula weigth ;) But you could rather use density, since octane is liquid, isn't it?

Simply, if you have 10% aceton (e.g. 10 ml of acetone + 90 ml of water), you add just 1 g of the octane to the 100 ml (you should better fill it up to 100 ml).

Cis or trans? That's what matters.
