Determine the molarity of an antifreeze ...

Determine the molarity of an antifreeze solution containing 250 g water mixed with 222 g ethylene glycol `(C_(2)H_(6)O_(2))`. The density of the solution is 1.07 g/mL.

Text Solution

Verified by Experts

The correct Answer is:
8.12 M
Total mass of solution = `250+222g = 472g" , Total volume of solution "=(472)/(1.07)mL=441.1 mL`
`"Molarity "=(222g)/("62 g mol"^(-1))xx(1)/("441.1 mL")xx"1000 mL"="8.12 M."`
