    The easiest way to do these is to remember the conversion that
1 ppm = 1 mg/L
0.0972 g/100 g H2O = 0.0972/100 mL = 0.972 g/L = 972 mg/L = 972 ppm
    
1 ppm = 1 mg/L
0.0972 g/100 g H2O = 0.0972/100 mL = 0.972 g/L = 972 mg/L = 972 ppm

    You can just divide 0.0972 g by 100 g and then multiply that number by 1 million because ppm= grams of solute/grams of solution  x 1,000,000.
