3% solution of glucose is isotonic with ...

`3%` solution of glucose is isotonic with `1%` solution of non-volatile non-electrolyte solute. The molecular mass of the solute would be
a.`180`, b.`160`,c.`120`, d.`60`

Text Solution

Verified by Experts

d.`pi_("glucose")=pi_("solute")`
`C_("glucose")=C_("solute")`
`((W_(B)xx1000)/(Mw_(B)xxV))_("glucose")=((W_(B)xx1000)/(Mw_(B)xxV))_("solute")`
`((3xx1000)/(180xx100))_("glucose")=((1xx1000)/(Mw_(B)xx100))_("solute")`
`Mw_(B)("solute")=60`
