somy · Answer

concentration is molarity (in case if u didnt know) 
so 
conc= mole/dm3 
dm3 is the unit of volume that is to be used in this formula 
you are given mass  
you know the compound thus can calculate its Molecular mass using periodic table 
then 
mole = mass/ Molecular mass 
this way you will find mole 
so 
now you have volume converted to dm3 
and you calculated mole 
so use concentration formula above & get your final answer of molarity (or concentration, whatever u call it)

Btw @Cassandra_Lea_96, 1 dm3 = 1 L
