Question

In this lab experiment you will make 100.0 mL of a 0.100 M solution of Co(NO3)2. However you must calculate the number of moles of compound that will be needed (moles= Molarity x Liters).Then calculate the mass of Co(NO3)2 that will need to be weighed out (mass= moles x molar mass)

CAN SOMEONE PLEASE EXPLAIN TO ME HOW TO DO THIS??

Answer 1

I shall be happy to help if you explain what your problems are. The question clearly tells you, at least in my opinion, exactly what to do.

Answer 2

thanks! But it turns out I was over thinking it!
