The mass ofa nonvolatile solute of malar mass 40g/mol that should be dissolved in114g of octane to lower its vapour press.by 20% is......... a) 10 g b)11.4 g c)9.8 g d)12.8 g

Question

Vikas TU · Answer

From partial pressure for non volatile solute formulae: (P – xP)/P = nA/nB (P – 0.2P)/P = (w/40)/(114/114) 0.8 = w/40 w = 32 g.
