Solve 10a - 5b = 25 for b. f) b = 10a + 25 g) b = 10a - 25 h) b = 2a +5 i) b = 2a - 5 What exactly are they asking me to do here? Can I get at least one with a step by step, then I'll do the others? And, then you can check my answers. Thanks :)

98. ## Chemistry

I dissolved 4g of solid NaOH in 200mL of water. I converted grams of NaOH to moles by 4g/40g/moles= 0.1moles. I calculated the concentration of NaOH by 0.1/(200mL/1000L)= 0.5 moles/L. I now have to record the expected mass of benzoic acid required to react
