Answer
One US teaspoon (4.93 ml) of cornstarch weighs 2.67 grams, from USDA FoodData Central, SR Legacy entry 169698 “Cornstarch”, portion “1 cup” = 128 grams, and 1 US cup = 48 US teaspoons.

This is the level US teaspoon of 4.93 ml. A recipe written for the metric teaspoon of 5 ml means 1.4 % more: 6.76 grams.
How 2 1/2 teaspoons of cornstarch was converted to grams
One US teaspoon of cornstarch weighs 2.67 grams (two point six seven), so multiply 2 1/2 by (128 ÷ 48).
2 1/2 × (128 ÷ 48) g
≈6.67 grams
(six point six seven grams)
The weight of the teaspoon comes from USDA FoodData Central, SR Legacy entry 169698 “Cornstarch”, portion “1 cup” = 128 grams, and 1 US cup = 48 US teaspoons. Scooped ingredients vary with how they are filled — spooned in lightly, a teaspoon weighs less; packed down, more — so for baking a kitchen scale is the exact tool and this figure the standard reference.

The other way round: how many teaspoons a weight fills
This page starts from teaspoons and answers in grams. The opposite question — how many teaspoons a weight from a recipe fills — is what the grams to teaspoons converter is for. Both read the same USDA weights, so their numbers agree: 100 grams of cornstarch is 37.5 teaspoons there.
