Homework Help: Chemistry

Posted by Melissa on Monday, November 19, 2012 at 1:22pm.

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??
