Calculate the molarity the following solution 30g Co(NO_3)_2.6H_2O in – InterviewSolution

1.	Calculate the molarity the following solution 30g Co(NO_3)_2.6H_2O in 4.3L of solution
Answer» Solution :MOLAR mass of `CO(NO_3)_2.6H_2O`= `59+ 2(14+48)+ 6xx18=291` `therefore` Molarity=`W_1/ (M_1xxV)`(in L) = `30/(291xx4.3)= 0.024`
