Respuesta :

Answer: 11.66g

Explanation:

Number of mole= Mass/Molar Mass

Molar Mass of Na2CO3 = (23*2)+12+(16*3)
                                         = 106g/mol
0.11moles = Mass/(106g/mol)
Mass= 0.11*106
Mass= 11.66g

Molar mass

  • 2(23)+12+3(16)
  • 106g/mol

Mass:-

  • No of moles ×Molar mass
  • 0.11(106)
  • 11.66g
