Respuesta :
The relative atomic mass of x is 101 u.
Molar mass is calculated by adding the atomic mass of all the elements in a compound.
Molar mass of x(HCO₃) =162 g/mol
Atomic mass of H = 1 g/mol
Atomic mass of C =12 g/mol
Atomic mass of O = 16 g/mol
Therefore, molar mass of x(HCO₃) will be
= x + 1 + 12 + 3 x 16
We know that:
x + 1 + 12 + 3 x 16=162
x + 61 = 162
x = 101 g/mol
The relative atomic mass of x will be 101 u.
