Objective

To remake the CuSO4·5H2O and Ha2SO4 standards

Description

  • See below for calculations


Data

No data was collected today.

Calculations

20 ppm SO42- = 20 mg/L SO4 · 0.5 L = 10 mg SO42- · .1 g /1000 mg = 0.01 g SO42-

0.01 g SO42- ÷ 96.06 g/mole = 1.041 × 10-4 moles SO42- · 1 mole CuSO4·5H2O / 1 mole SO42-
