What mass of ethylene glycol (molar mass...

What mass of ethylene glycol (molar mass = 62.0 g `mol^(-1)` ) must be added to 5.50 kg of water to lower the freezing point of water from `0^(@)C ` to `- 10.0^(@)` C ?
`(K_(f) "for water " = 1.86 k " kg mol"^(-1))`

Text Solution

Verified by Experts

`W_(B) = ?, M_(B) = 62 , W_(A) = 5.50 g `
`Delta T_(f) = 10^(@) C, K_(f) = 1.86`
`Delta T_(f) = K_(f) xx (W_(B))/(M_(B) xx W_(A))`
10 = `1.86 xx (W_(B))/(62 xx 5.50) `
3410 = 1.86 `W_(B)`
`W_(B) = ` 1833.3 = 1.833 kg
