The empirical formula for a compound is C2H4NO If its molar mass is 2322 gmol what is the molecular formula of the compound class=

Respuesta :

Empirical formula mass

  • C2H4NO
  • 2(12)+4(1)+14+16
  • 30+24+4
  • 58g/mol

Molar mass=232.2g/mol

Find n

  • Molar mass/Empirical formula mass
  • 232.2/58
  • 4

Molecular formula

  • n×Empirical formula
  • 4(C2H4NO)
  • C8H16(NO)_4

Find the empirical formula mass

  • 2(12u)+4(1u)+14u+16u
  • 58u or 58g/mol

Find n

  • Molar mass/Empirical mass
  • 232.2/58
  • 4.05

Round to nearest whole

  • n=4

Molecular formula

  • 4(C2H4NO)
  • C8H16N4O4
