Solvent mixtures - How do you determine (theoretically and/or experimentally) the dipole moment or dielectric constants of solvent mixtures?

If I mix, for example, CS2 (Dipole moment 0, dielectric constant 2.6) with toluene (Dipole moment 0.36, dielectric constant 2.38) in a certain ratio, what would be the d.m. and d.c. of the...

I have two layers of different materials (graphene & hBN) stacked together. Can I confirm that the layer beneath the upper layer is graphene by AFM?

I am not sure how thick my graphene is, but the hBN is a single layer. I think that the transfer process wasn't so 'good'. Nevertheless, hBN covers the graphene flakes. Now I need to confirm that...
