Great solvable question. Simply use the formula: #n=m/M#

Always use a periodic table as a reference when dealing with moles and mass numbers of the elements or compounds.

Explanation:

Phosphorus has a molar mass #(M)# of #"30.973762 g/mol"#.

Therefore

#m=n xx M= "2.3 moles" xx "30.973762 g/mol" = "71 g"#
