Textbook Question

Chapter 4, Problem 113IE

Although there are many ions in seawater, the overall charges of the dissolved cations and anions must maintain charge neutrality. Consider only the six most abundant ions in seawater, as listed in Table 18.5 (CI^-, Na⁺, SO₄²^-, Ca²⁺, and K⁺), calculate the total charge in Coulombs of the cations in 1.0 L of seawater. Calculate the total charge in Coulombs of the anions in 1.0 L of seawater. To how many significant figures are the two numbers equal?

I'm trying to memorize VESPR Shapes to solve problems like those. I need help making circles like the second image in blue or using an x- and y-axis plane to memorize these and solve those types of problems, especially the ones given in the top/first image (180, 120, 109.5). Can you help me with this? or is their any other efficient method do so

Can you please explain this problems to me? I'm very confused about it. Please provide a detailed, step-by-step explanation for me! (ME EX1) Prblm 27
