Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: Because outside a typical cell‚ the concentration of K+ is about 5mM and the concentration of Na+ is about 150 mM. When you increase the concentration of K+ from 5 to 25 mM and reduce concentration of Na+ from 150 to 130 mM‚ the outside has more concentration of K+. The membrane is permeable to a particular ion‚ that ion will diffuse down

Steps: 1) Determine how many atoms of each element are within the compound. 2) Determine the molar mass of each element. 3) Multiply the molar mass of each element by how many atoms of that element are within the compound. 4) Add up the numbers produced in step three. Ex. 1: Calculate the molar mass of C6H4Cl2. 1) 6 C atoms‚ 4 H atoms‚ 2 Cl atoms 2) C = 12.01 g‚ H = 1.01 g‚ Cl = 35.45 g. 3) C = 6 ×
