To find the atomic mass of X, we can first calculate the atomic mass of Na, O, and the whole compound.
The atomic mass of Na is 23 g/mol.
The atomic mass of O is 16 g/mol.
The atomic mass of the entire compound Na2X2O3 can be calculated as:
(2 x Na) + (2 x X) + (3 x O) = 158 g/mol
(2 x 23) + (2 x X) + (3 x 16) = 158
46 + 2X + 48 = 158
94 + 2X = 158
2X = 64
X = 32
Therefore, the atomic mass of element X is 32 g/mol.
The atomic mass of Na is 23 g/mol.
The atomic mass of O is 16 g/mol.
The atomic mass of the entire compound Na2X2O3 can be calculated as:
(2 x Na) + (2 x X) + (3 x O) = 158 g/mol
(2 x 23) + (2 x X) + (3 x 16) = 158
46 + 2X + 48 = 158
94 + 2X = 158
2X = 64
X = 32
Therefore, the atomic mass of element X is 32 g/mol.
