... Hint: See both 5th ed. and 6th ed. Section 9.3. In the formula, Ca(NO3)2, it indicates there are 1 Ca, 1x2 = 2 N and 3x2 = 6 O. Go to the periodic table and locate the atomic mass for each atom. Thus the formula mass of Ca(NO3)2 = 1x40 + 2x14 + 6x16 = 164. Note that if the unit given as amu (referri ...
