Answer #1

Mgo has Nacl type crystal structure, for which Z=4, molar mass of Mgo=24+16=40, edge length is provided in question,

Hence density =(Z*molar mass) /avagadro number * a^3

Where a is edge length.

Now for cscl z=1 molar mass=168

Apply same formula.

Note-take care of units.

I hope it helps you, please give me a positive feedback

4. The cell membrane can be modeled like an electrical circuit. The phospholipid mem- brane can be represented by a capacitance CM. Each ion gradient can be represented as a current -GiVi where i represents a given ion, I is current, V is voltage, and G is conductance. (As a reminder, conductance is the inverse of resistance.) First, consider a model with one ion: (a) Find the transfer function for the figure shown above (b) In the 1950's Alan Hodgkin...
