Molarity = number of moles of solvent / volume of solution (in liters)
We have the volume of solution = 350 ml = 0.35 liters and the molarity = 3 m
Substituting in the equation, we get:
3 = number of moles / 0.35
number of moles = 3 x 0.35 = 1.05moles
Answer:
3 and 1.5 gallons respectively
Explanation:
City driving = 18/6 = 3 gallons
Highway driving = 27/18 = 1.5 gallons
