In winter, the normal temperature in Kashmir valley is ` - 12^(@)` C . Is a `25% ` by mass of an aqueous solution of ethylene glycol (molar mass = 62) suitable for car radiator . `K_(f)` for water is `1 . 86 Km^(-1)`

Text Solution

Verified by Experts

`W_B = 25g `
`M_B = 62`
`W_A =75 g`
`K_f =1.86`
`DeltaT_f=(K_fxxW_Bxx1000)/(M_BxxW_A)`
`=(1.86xx25xx1000)/(62xx75)`
`DeltaT_f=10K`
