Calculations:

20.53mg/ml of copper sulfate so multiple by weight of sulfate to get concentration of sulfate in solution

  • 20.53mg/l*1mol/.09606mg= 208.20 mol/L

To find the concentration of copper for our standers multiple concentration of sulfate to copper weight

  • 208.20mol/L *0.063546 mg/mol= 13.23mg/l or ppm
