(10 mgNO_3)/(Liter) = ((0.01gNO_3)/(1000g"Soln"))

In each of the following, note how the ratio (in common units) is multiplied by the factor needed; that is,
=> pph = ratio x 100 => %
=> ppm = ratio x 1-million
=> ppb = ratio x 1-billion

=> %NO_3 = Parts per Hundred = ((0.01gNO_3)/(1000g"Soln")) x 100% = 1xx10^-3%(NO_3) or 1xx10^-3 parts per hundred (pph)

=> Parts per Million ("ppm") = ((0.01gNO_3)/(1000g"Soln")) x 10^6("ppm") = 10 ppm

=> Parts per Billion ("ppb") = ((0.01gNO_3)/(1000g"Soln")) x 10^9("ppb") = 10000 ppb

=> Molarity(M) = "moles"/"Liter" = ((0.01gNO_3)/(62(g)/(mol)))(L^-1) = 1.61xx10^-4M
