what mass TiO2 needs to be dissolved in water to make 0.45 mL of a 0.700 M TiO2 solution

what mass TiO2 needs to be dissolved in water to make 045 mL of a 0700 M TiO2 solution class=

Respuesta :

  • Volume=0.45mL=0.00045L
  • Molarity=0.7M

No of moles:-

[tex]\\ \tt\Rrightarrow Molarity (Volume)[/tex]

[tex]\\ \tt\Rrightarrow 0.00045(0.7)[/tex]

[tex]\\ \tt\Rrightarrow 0.000315mol[/tex]

  • Molar mass of TiO_2=79.866g/mol

Mass:-

  • 0.000315(79.866)=0.025157779g
