The relative formula mass of #"C"_5"H"_10"N"# is #84.14#.

Explanation:

#"C"_5"H"_10"N"#

Determine the relative formula mass by multiplying the subscript for each element by the relative atomic mass #("A"_"r")# found on the periodic table. Relative atomic mass is dimensionless

Relative Atomic Masses

#"C":# #12.011#
#"H":# #1.008#
#"N":# #14.007#

Relative Formula Mass

#(5xx12.011)+(10xx1.008)+(1xx14.007)=84.14# rounded to two decimal places #(10xx1.008)=10.08)#
