Hello. This is a difficult mixture problem. The following link directs you to a SIMILAR problem. I how it offers a general idea:

Eine DNA-Lösung mit 800 ng / ul, und Sie möchten 0,01 mg DNA in einer Reaktion verwenden. Wie viele Mikroliter Ihrer DNA-Lösung sollten Sie verwenden?

Hello Guest!

$$\frac{800ngDNA}{\mu l}\cdot\frac{10^3mg}{10^9ng}=\frac{8\cdot 10^{-4}mg\ DNA}{\mu l}$$

$$0.01mg\ DNA:\frac{8\cdot 10^{-4}mg\ DNA}{\mu l}=\color{blue}12.5\ \mu l$$

$$12.5\ microliters\ of\ your\ DNA\ solution\ should\ you\ use.$$

.01 mg  = 10 microgram = 10 000 nanograms

10 000 nanograms  /  800 nanograms/microliter = 12.5 microliters
