Objective

1) XRay analysis of 100% and 50% CEC surfactant Clay 2) Standard solution of CuSO4 calculations

Description

2) standard solution calculations for dilution of stock solution of CuSO4*5H2O Enter the Page Title Here

Standard #CuSO4*5H2O (mL)H2O(mL)3m1v1=m2v2Concentration (ppm)
10.259.75(.013581g/ml)(.25ml)=x(10ml)0.00033953 g/ml=.339525ppm
20.509.50(0.013581g/ml)(.5ml)=x(10ml)0.000679g/ml=.679ppm
31.009.00(0.013581g/ml)(1ml)=x(10ml).0013581g/ml=1.358ppm
42.008.00(0.01358g/ml)(2ml)=x(10ml).002716g/ml=2.716ppm
53.007.00(0.01358g/ml)(3ml)=x(10ml).004074g/ml=4.074ppm
67.003.00(0.01358mg/ml)(7ml)=x(10ml).009506g/ml=9.5ppm
710.000(0.01358g/ml)(10ml)=x(10ml).01354g/ml=13.58ppm

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
