You rent a car in germany with a gas mileage rating of 12.8km/l. what is its rating in miles per gallon?

The mileage rating of the car is 30.05 miles per gallon

Explanation:

We are given:

Mileage rating = 12.8 km/L

To convert this level into milligrams per deciliters, we use the conversion factor:

1 mile = 1.61 km

1 gallon = 3.78 L

Converting the above rating into miles per gallon, we get:

Hence, the mileage rating of the car is 30.05 miles per gallon

so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah

6.51g

Explanation:

0.125 M = 0.125 mol/1000ml

0.125/4 = 0.03125 mol

BaCl2:

Mr = 137.3 + 2(35.5) = 208.3

mass = 208.3(0.03125) = 6.509375
