Answer:
= 155 ppm
Explanation:
PPM also refers to parts per million, it represents a low concentration of a solution. It represents 0.001 gram or a milligram in a 1000 mL, equivalent to 1 mg per liter
Given that;
101 mg of Ca in 650.0 g of water
1 ppm = 1 mg/L
650 g = 650 mL = 0.65 L
Therefore;
= 101 mg/ 0.65 L
= 155.38 mg/L
<u>= 155 ppm</u>
