Question

A is a metal with a mass of 24.31g/mol and B is a nonmetal with a mass of 35.45 g/mol.

What is the molar mass of AB2?


A.95.21 g/mol

B.84.07 g/mol

C.59.76 g/mol

D.106.35 g/mol

Answer 1

Answer:

95.21

AB2 MOLECULE consists of one atom of A and two atom of B .

so molar mass of AB2=( MOLAR MASS OF A) + 2×(MOLAR MASS OF B)

=(24.31)+2×(35.45)

=95.21
