This is based on 1 cup of powdered sugar = 120 g, so 2/3 cup of powdered sugar is 2/3 × 120 ≈ 80 g.

How to measure 2/3 cup of powdered sugar

By weight (most accurate): set your bowl on a kitchen scale, press tare, and add 80 g of powdered sugar.

By volume: Use a 1/3-cup measure twice, or 10 tablespoons plus 2 teaspoons.

Powdered (confectioners’) sugar is fine and airy, so a cup weighs far less than a cup of granulated sugar. Sift it if the recipe says “sifted”.

Why powdered sugar weighs what it does

Powdered sugar is about 49% lighter than the same volume of water, which weighs about 237 g per cup. That is why you can't convert cups to grams without knowing the ingredient.
