please give step by step solution especially at the RT/F part because I do not understand what values are being used

The following concentration values in mM have been measured: [K+]in=168;[K+]out=6.0;[Na+]in=50.7;[Na+]out=337;[Cl]in=41.4;[Cl]out=340; At rest, the permeabilities have the following ratio: PK:PNa:PCl=1.0:0.03:0.35. Q1.1) Solve for Vrest.. Q1.2) By how much would Vrest increase when [K+]out= 60.0? Q1.3) Given gK=0.57uS,gNa=0.11uS, and gCl=0.32uS, solve for Vrest using the Parallel Conductance Model The following concentration values in mM have been measured: [K+]in=168;[K+]out=6.0;[Na+]in=50.7;[Na+]out=337;[Cl]in=41.4;[Cl]out=340; At rest, the permeabilities have the following ratio: PK:PNa:PCl=1.0:0.03:0.35.
