I really need SOMEONE to explain each STEP by STEP... PRETEND I AM FIVE YEARS OLD. If you do 5+5, please SHOW THE STEPS!! Don't just assume I would know how the math would work. SHOW WHERE THE NUMBERS COME FROM... if you are plugging in 8 mg/L PLEASE state where the number came from. My algebra isn't the greatest so showing the steps is going to help me understand what is happening. I will thumbs down anyone that ignores these directions or does not get 1.49 as a close answer.

You are hired as an environmental engineer to test a water sample to determine its potential to form precipitates. If the calcium concentration in this water sample is 8 mg/L, determine maximum allowable carbonate (CO_3^2-) concentration (in mg/L) to prevent any CaCO_3 precipitation in the pipes. Correct Answer: 1.49 make sure you ultimately get this answer! Or I will thumbs down!

You are hired as an environmental engineer to test a water sample to determine its potential to form precipitates. If the calcium concentration in this water sample is 8mg/L, determine maximum allowable carbonate (CO32) concentration (in mg/L ) to prevent any CaCO3 precipitation in the pipes. Enter your final answer with 2 decimal places
