(A) The molar mass of $H_3PO_4$ is given as $98 \ g/mol$.The formula for molar mass is: $3 \times \text{Atomic mass of } H + 1 \times \text{Atomic mass of } P + 4 \times \text{Atomic mass of } O = 98 \ g/mol$.Given atomic masses: $H = 1 \ g/mol$,$O = 16 \ g/mol$.Substituting the values: $3(1) + P + 4(16) = 98$.$3 + P + 64 = 98$.$67 + P = 98$.$P = 98 - 67 = 31 \ g/mol$.
