Depends on the mix. A complete pancake mix may contain oil and powdered milk, while Hungry Jack Extra Light pancake mix has you add milk and oil.
Alton Brown, whose recipes generally are extremely highly regarded, has a recipe for pancake mix which you can find with your favorite search engine. He says you need two cups of mix to make 12 pancakes. At that rate, 1/3 cup of mix will make 2 pancakes.
But how big is a pancake? Is it a "silver dollar"pancake, about 2" in diameter and nearly paper thin? Is it the extra-large-Pizza size pancake John Candy turned with a pizza spade in "Uncle Buck"? Is it toaster-size, like most frozen pancakes, large as a dinner place, or rhe size of a salad plate, like many truck stops seem to produce? I tend to make 'em dinner plate size, in a 16" cast iron skillet, but I never know what it means when recipes specify how many waffles the recipe produces.

If you are asking, "How many 1/3 cups of milk are in a half a cup of milk", then the answer is one. But if you are asking if 1/2 cup of milk can be divided into thirds, then yes it can, and you would have 3 thirds.
5.28 oz1 cup = 8 ounces 1 ounce = 0.12 cup
That is approximately 31.968 teaspoons.
Half of one and two thirds of a cup would be five sixths of a cup.
