Answer:

47.01g/mol

Explanation:

The formula of Nitrous acid is HNO₂:

The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.

Atomic mass of H = 1.0079g/mol

                          N = 14.0067g/mol

                          O = 15.9994g/mol

Formula mass of HNO₂ = 1.0079 +  14.0067 + 2(15.9994)

                                        = 1.0079 +  14.0067 +31.9988

                                         = 47.01g/mol
