Question

Mass of
Colnd ( _{3} ) ) ( 2 cdot 6 mathrm{k}_{2} mathrm{O} )
nrass of ( (0=58.93 mathrm{g} / mathrm{mol} )
nacus of ( n=1481 ) mol 0.3 ub ( 0=16 ) glmot.
So mass of ( cos 103.06120 )
( =58.93+124+64181 )
( =58.93+124+108=290.9391 mathrm{mot} )

# What is the Molar mass of - Co (NO3)2.640
