To what volume should you dilute 125 ml of an 8. 20 m cucl2 solution so that 50. 5 ml of the diluted solution contains 4. 66 g cucl2? express your answer in milliliters.

Answers:
a- Mrs Walter's milage per gallon = 14.4 miles/gallon
b- Mr Walter's milage per gallon = 15 mile/gallon
c- Mr Walter's car has better milage per gallon

Explanation:
Part (a):
We are given that:
distance = 360 miles
number of gallon = 25 gallons
Therefore,
the miles/gallons can be simply obtained by dividing the given miles by the used gallons as follows:
miles/gallons for Mrs Walters = 360 / 25 = 14.4 miles/gallon

Part (b):
We are given that:
miles = 480 miles
number of gallons = 32 gallons
Therefore,
the miles/gallons can be simply obtained by dividing the given miles by the used gallons as follows:
miles/gallons for Mr Walters = 480 / 32 = 15 miles/gallon

Part (c):
Mrs Walter's car can move 14.4 miles using one gallon of gas
Mr Walter's car can move 15 miles using one gallon of gas
Comparing the two values, we will find that Mr Walter's car can move more miles using the same amount of gas when compared to Mrs Walter's car.
Therefore, Mr Walter's car has the better milage per gallon

Hope this helps :)
