Hello!
Percentage error = (true value - measured value)/true value x 100%
Percentage error = (27.7-27.0)/27.7 x100% = 25.3%
The coordination number is 6. The outer Cl- ion isn't included, so you count 4 x NH3 and 2 x Cl- are within Co's coordination sphere.
molaity= moles/L
molarity= 5.0 moles/ 10 L
molarity= 0.5
Should be :
Lead Sulfate Tetrahydrate
a. Solid to liquid - melting process
b. Liquid to gas - evaporation process
c. Gas to solid - deposition process
d. Solid to gas - sublimation process
e. Liquid to solid - solidification process
f. Gas to liquid - condensation process
