#193g.mol#

Explanation:

Formula unit mass is a sum of the atomic mass of the atoms in a compound. It is another way of saying molecular weight.

To find the formula unit mass of #CsCO_3#, add the mass of cesium, carbon and 3 oxygen together.
#Cs = 132.9055g.mol#
#C= 12.0107g.mol#
#O=15.9994g.mol#

#= 132.90545 + 12.0107 + (15.9994 xx3)#
#=192.9143519g.mol => 193g.mol#

I hope this helps.
