Seawater contains 0.412 g Ca per kilogram of water. What is the number of moles of Ca per kilogram of water? What is the concentration of Ca measured in ppm?
For the first question, it's changing the grams of Ca to moles of Ca. Is it .412 g / 39 g = .0105 moles.
For the second question, I know the seawater formula is NaCl + H2O = 76g. So is it 76g/0.412 g (10^6).
