#"164.086 g/mol"# is the molar mass of calcium nitrate, #"Ca(NO"_3)_2"#

Explanation:

The molar mass of #"Ca(NO"_3)_2# is calculated by multiplying the molar mass of each element by its subscript (remember to multiply the subscripts for #"NO"_3"# by #2#) and adding the results. The molar mass of an element is its atomic weight on the periodic table in grams/mole, or g/mol.

#"Molar mass Ca":# #(1xx40.078 "g/mol Ca")+(2xx14.007"g/mol N")+(6xx15.999"g O")="164.086 g/mol"#
