Question

the molecular mass of X is 106 X can be​

Answer 1

Answer:

The question is incomplete, here is the complete question:

The molecular mass of x is 106, x can be:

A.) Na₂CO₃ (B) CaCO₃ (C) NaCl (D) C₂H₅OH

The compound X having molar mass 106 g/mol is Na_2CO_3

Explanation:

Molecular mass is defined as the mass which is calculated by the addition of masses of respective elements, each multiplying by its number of atoms.

For the given options:

Option A: Na_2CO_3

Molar mass of sodium carbonate = (2\times 23)+(1\times 12)+(3\times 16)]=106g/mol

Option B: CaCO_3

Molar mass of calcium carbonate = (1\times 40)+(1\times 12)+(3\times 16)]=100g/mol

Option C: NaCl

Molar mass of sodium chloride = (1\times 23)+(1\times 35.5)]=58.5g/mol

Option D: C_2H_5OH

Molar mass of ethanol = (2\times 12)+(6\times 1)+(1\times 16)]=46g/mol
