Define molal elevation constant or ebullioscopic constant.

A

the elevation in b.p. which would be produced by dissolving one mole of solute in `100`g of solvent

B

the elevation in b.p. which would be produced by dissolving `1` mole of solute in `10`g of solvent

C

the elevation in b.p. which would be produced by dissolving `1` mole of solute in `1000`g of solvent

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaT_(b)=(1000K'_(b)xxw)/(m.W),if w//m=1`
`W=1000g.`
`DeltaT_(b)=K'_(b)`
