Exercício de PPM

por Luci (PROUNI) Normal Monday, June 1st, 2020


O nitrogênio é um elemento indispensável para o crescimento de algas, podendo, em certas condições, conduzir ao fenômeno de eutrofização de lagos e represas, causando odor desagradável. Na forma de nitrato ( NO3 ) a concentração maxima permitida pela Ligislação Brasileira em rios é de 10 mg/L (ou por g de H2O). Na amostra analisada do rio, você identificou uma certa concentração de nitrato de 55mg/L, portanto, acima do aceitável. Como você descreveria no seu relatório este valor em ppm (partes por milhão)?
