Molar mass:-

[tex]\\ \sf\longmapsto HC_2H_3O_2[/tex]

[tex]\\ \sf\longmapsto 1u+2(12u)+3(1u)+2(16u)[/tex]

[tex]\\ \sf\longmapsto 1u+24u+3u+48u[/tex]

[tex]\\ \sf\longmapsto 28u+48u[/tex]

[tex]\\ \sf\longmapsto 76u[/tex]

[tex]\\ \sf\longmapsto 76g/mol[/tex]

  • No of moles=0.2mol
  • Given mass=?

[tex]\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:Mass}{Molar\:Mass}[/tex]

[tex]\\ \sf\longmapsto 0.2=\dfrac{Given\:mass}{76}[/tex]

[tex]\\ \sf\longmapsto Given\:Mass=0.2\times 76[/tex]

[tex]\\ \sf\longmapsto Given\:Mass=1.52g[/tex]
