A solution of 100 ml of 1.17 % (W/V) NACL is prepared in a laboratory , calculate the NACL concentration in ppm?
1 ppm = 1 mg/L
1.17% NaCl(w/v) = 1.17 g NaCl/100 mL = 1170 mg NaCl/100 mL = 11700 mg NaCl/1000 mL = 11700 mg NaCl/L = 11700 ppm NaCl
1.17% NaCl(w/v) = 1.17 g NaCl/100 mL = 1170 mg NaCl/100 mL = 11700 mg NaCl/1000 mL = 11700 mg NaCl/L = 11700 ppm NaCl
