Answer to Question #151220 in General Chemistry for kevin T

Question

All of the chlorine in the compound CoCl2 [cobalt (II) chloride] represents what percent of the compound’s molar mass?

Answer 1

Solution:

$CoCl_2=129.8392( \tfrac{g}{mole} )$

$Cl_2=70.9060( \tfrac{g}{mole} )$

$\dfrac{70.9060( \tfrac{g}{mole} )}{129.8392( \tfrac{g}{mole} )} =0.5461*100\%=54.6\%$

Answer:

54.6% of chlorine in the chemical compound [cobalt (II) chloride].
