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
