Waste water sample contains 2.092 mmol/L NaCl. Calculate the concentration of NaCl in mg/L. What are the mmol/L concentrations of Na and Cl? (Na = 23, Cl = 35.5)
a) NaCl concentration = 58.8 mg/L, [Na] = 23 mmol/L, [Cl] = 35.5 mmol/L
b) NaCl concentration = 70.2 mg/L, [Na] = 23 mmol/L, [Cl] = 35.5 mmol/L
c) NaCl concentration = 46.4 mg/L, [Na] = 23 mmol/L, [Cl] = 35.5 mmol/L
d) NaCl concentration = 81.5 mg/L, [Na] = 23 mmol/L, [Cl] = 35.5 mmol/L
